I am using ASPOSE Slides in my project to perform a PPT task. I want to change my table header background-color but I have not found any solutions in Aspose forum for it. Can anybody provide me with the solution?
ISlide sld = press.Slides[0];
double[] dblCols = { 250, 250};
double[] dblRows = { 70, 70, 70,70 };
// Add table shape to slide
ITable tbl = sld.Shapes.AddTable(100, 100, dblCols, dblRows);
tbl[0, 1].TextFrame.Text = "some text";
tbl[0, 2].TextFrame.Text = "some text";
tbl[0, 3].TextFrame.Text = "some text";
tbl[0, 3].BorderBottom.FillFormat.FillType = FillType.Solid;
tbl[0, 3].FillFormat.SolidFillColor.BackgroundColor = Color.Blue;
tbl[0,3].BorderBottom.Width = 2;
Portion portion = (Portion)tbl[0, 1].TextFrame.Paragraphs[0].Portions[0];
portion.PortionFormat.FillFormat.FillType = FillType.Solid;
portion.PortionFormat.FillFormat.SolidFillColor.Color = Color.Black;
}
I have observed you requirements related to setting table header background. Please try using following sample code that has example of setting fill color for one of header row cell. You can replicate the same for other cells too.
public static void TestTableBackground()
{
Presentation press = new Presentation();
ISlide sld = press.Slides[0];
double[] dblCols = { 250, 250 };
double[] dblRows = { 70, 70, 70, 70 };
// Add table shape to slide
ITable tbl = sld.Shapes.AddTable(100, 100, dblCols, dblRows);
tbl[0, 1].TextFrame.Text = "some text";
tbl[0, 2].TextFrame.Text = "some text";
tbl[0, 3].TextFrame.Text = "some text";
tbl[0, 0].FillFormat.FillType = FillType.Solid;
tbl[0, 0].FillFormat.SolidFillColor.Color = Color.Blue;
Portion portion = (Portion)tbl[0, 1].TextFrame.Paragraphs[0].Portions[0];
portion.PortionFormat.FillFormat.FillType = FillType.Solid;
portion.PortionFormat.FillFormat.SolidFillColor.Color = Color.Black;
press.Save(#"C:\Aspose Data\TableFormat.pptx", Aspose.Slides.Export.SaveFormat.Pptx);
}

I am quite new to ASP.NET Charting and have a question about adding custom component to a bar chart. I am trying to create a custom legend in a tabular format. What I mean is my legend style is table. And I am creating each LegendItem from database values and adding it to chart.Legends[0].CustomItems collection.
I get the data but I am getting all the LegendItems in one row. I want to display each LegendItem on new row. My current code look like this -
chart.Legends.Add(new Legend
{
LegendStyle = LegendStyle.Table,
BorderColor = Color.Black,
BorderWidth = 1,
BorderDashStyle = ChartDashStyle.Solid,
Alignment = StringAlignment.Center,
DockedToChartArea = areaCounter.ToString(),
Docking = Docking.Bottom,
Name = "CustomLegend",
IsTextAutoFit = true,
InterlacedRows = true,
TableStyle = LegendTableStyle.Auto,
IsDockedInsideChartArea = false
});
LegendItem newItem = new LegendItem();
newItem.Cells.Add(LegendCellType.Text, " - value1 - ", ContentAlignment.MiddleCenter);
newItem.Cells.Add(LegendCellType.Text, " - State Average = - ", ContentAlignment.MiddleCenter);
newItem.Cells[1].CellSpan = 2;
newItem.BorderColor = Color.Black;
newItem.Cells.Add(LegendCellType.Text, " - ", ContentAlignment.MiddleCenter);
newItem.Cells.Add(LegendCellType.Text, " - top - ", ContentAlignment.MiddleCenter);
chart.Legends[1].CustomItems.Add(newItem);
LegendItem newItem1 = new LegendItem();
newItem1.Cells.Add(LegendCellType.Text, "value1", ContentAlignment.MiddleCenter);
newItem1.Cells.Add(LegendCellType.Text, "State Average =", ContentAlignment.MiddleCenter);
newItem1.Cells[1].CellSpan = 2;
newItem1.BorderColor = Color.Black;
newItem1.Cells.Add(LegendCellType.Text, "", ContentAlignment.MiddleCenter);
newItem1.Cells.Add(LegendCellType.Text, "top", ContentAlignment.MiddleCenter);
chart.Legends[1].CustomItems.Add(newItem1);
newItem and newItem1 both appear on same row as legend. Can you please help me solve this issue ? I'd really appreciate your help.
Found out that once I add HeaderSeparator to my custom Legend object and handle the chat object's CustomizeLegend event it worked as I wanted. The custom items are displayed on separate rows. Here are the changes that I did.
chart.Legends.Add(new Legend
{
LegendStyle = LegendStyle.Table,
BorderColor = Color.Black,
BorderWidth = 1,
BorderDashStyle = ChartDashStyle.Solid,
Alignment = StringAlignment.Center,
DockedToChartArea = areaCounter.ToString(),
Docking = Docking.Bottom,
Name = "CustomLegend",
IsTextAutoFit = true,
InterlacedRows = true,
TableStyle = LegendTableStyle.Tall,
HeaderSeparator = LegendSeparatorStyle.Line,
HeaderSeparatorColor = Color.Gray,
IsDockedInsideChartArea = false
});
LegendItem newItem3 = new LegendItem();
var strVal = item.Value;
foreach (var val in strVal)
{
newItem3.Cells.Add(LegendCellType.Text, val, ContentAlignment.BottomCenter);
}
chart.Legends["CustomLegend"].CustomItems.Add(newItem3);
chart.CustomizeLegend += chart_CustomizeLegend;
void chart_CustomizeLegend(object sender, CustomizeLegendEventArgs e)
{
Chart chart = sender as Chart;
if (chart == null) return;
foreach (var item in e.LegendItems)
{
item.SeparatorType = LegendSeparatorStyle.Line;
item.SeparatorColor = Color.Black;
}
}
Hello guys I have a problem with core plot in xamarin. I managed to create a graph like below:
click here for the graph
I'm using this code:
/// <summary>
/// Configure the Axes of the graph
/// </summary>
void SetupAxes()
{
var plotspace = _graph.DefaultPlotSpace;
plotspace.AllowsUserInteraction = true;
var axisSet = (CPTXYAxisSet)_graph.AxisSet;
// Label x with a fixed interval policy
var x = axisSet.XAxis;
x.LabelingPolicy = CPTAxisLabelingPolicy.None;
x.Title = "X Axis";
x.TitleOffset = 0;
x.MinorTickLength = 5f;
x.MajorTickLength = 7f;
x.LabelOffset = 3;
x.MajorIntervalLength = 5;
x.MinorTicksPerInterval = 4;
// Label y with an automatic label policy.
var y = axisSet.YAxis;
y.LabelingPolicy = CPTAxisLabelingPolicy.None;
y.LabelOffset = 0;
y.Title = "Y Axis";
y.TitleOffset = 0;
y.MinorTickLength = 5f;
y.MajorTickLength = 7f;
y.LabelOffset = 3;
y.MajorIntervalLength = 5;
y.MinorTicksPerInterval = 4;
}
/// <summary>
/// Set up data source and configure plots
/// </summary>
void SetupBarPlots(List<float> inputSocket)
{
var barPlot = new CPTBarPlot
{
DataSource = new BarSourceData(inputSocket),
BaseValue = 0,
BarOffset = (NSDecimal)(-0.25),
Identifier = (NSString)"Bar Plot 1"
};
_graph.AddPlot(barPlot);
barPlot.Fill = new CPTFill(CPTColor.BrownColor);
_graph.AddPlot(barPlot, _graph.DefaultPlotSpace);
var space = _graph.DefaultPlotSpace as CPTXYPlotSpace;
space.ScaleToFitPlots(new CPTPlot[] { barPlot });
//get the highest value in the input data
var yMax = (decimal)inputSocket.Max();
decimal newYMax = yMax*2;
space.YRange = new CPTPlotRange(-20, new NSDecimalNumber(newYMax.ToString()).NSDecimalValue);
decimal newXMax = (decimal)space.XRange.MaxLimit + 2;
decimal newXMin = (decimal)space.XRange.MinLimit - 1;
space.XRange = new CPTPlotRange(new NSDecimalNumber(newXMin.ToString()).NSDecimalValue,
new NSDecimalNumber(newXMax.ToString()).NSDecimalValue);
//RectangleF(position x, position y, width, height
//AddSubview = adding a view on top of a View
_view.AddSubview(new CPTGraphHostingView(new RectangleF(20, 320, 662, 320))
{
HostedGraph = _graph
});
}
I want to show y value in the graph (red square in the image) so it could look like a proper graph. Anyone has an experience how to create graph using Xamarin/monotouch? There is not quite a lot of xamarin tutorial for core plot. Thanks before :)
Turns out I have to set labellingPolicy to Automatic. See below:
y.LabelingPolicy = CPTAxisLabelingPolicy.Automatic;
Then it will set the y axis value based on the data.
I am using asp.net chart control to display chart on my website , below is the snippet of it:
The issue is i want to add the text and an arrow line on each point , so for instance on the point (60,october) I want to write text at this point: projection was highest and an arrow image.
Is it possible to acheive something like this, any suggestion or assistance will be highly appreciated, below is the code i have used to generate this chart:
double[] yValues = { 15, 60, 12, 13 };
string[] xValues = { "September", "October", "November", "December" };
chart.Width = 500;
chart.Height = 200;
chart.BorderSkin.SkinStyle = BorderSkinStyle.FrameThin1;
ChartArea ca = new ChartArea();
ca.Name = "Default";
ca.AxisX.LineColor = System.Drawing.ColorTranslator.FromHtml("#FEFEFE");
ca.AxisX.LineWidth = 3;
ca.AxisX.MajorGrid.LineDashStyle = ChartDashStyle.Dash;
ca.AxisX.MajorGrid.Enabled = false;
ca.AxisX.MajorTickMark.LineWidth = 2;
ca.AxisX.LabelStyle.Format = "L";
ca.AxisY.LineColor = System.Drawing.ColorTranslator.FromHtml("#FEFEFE");
ca.AxisY.LineWidth = 3;
ca.AxisY.MajorGrid.Enabled = true;
ca.AxisY.MajorTickMark.LineWidth = 2;
ca.AxisY.Title = "yaxis";
chart.ChartAreas.Add(ca);
Legend legend = new Legend();
chart.Legends.Add(legend);
Series series = new Series("Series1");
series.IsValueShownAsLabel = false;
series.MarkerStyle = MarkerStyle.Circle;
series.BorderWidth = 5;
series.ChartType = SeriesChartType.Line;
series.ShadowOffset = 2;
series.XValueType = ChartValueType.String;
series.YValueType = ChartValueType.Double;
series.Font = new System.Drawing.Font("Trebuchet MS", 8);
series.BorderColor = System.Drawing.ColorTranslator.FromHtml("#33CCFF");
series.Color = System.Drawing.ColorTranslator.FromHtml("#33CCFF");
chart.Series.Add(series);
chart.Series["Series1"].Points.DataBindXY(xValues, yValues);
chart.DataManipulator.InsertEmptyPoints(1, System.Web.UI.DataVisualization.Charting.IntervalType.Days, "Series1");
You need to search for the largest data point and use property
datapoint.Label = "projection was highest";
Also easiest way to highlight the point is to use datapoint.MarkerStyle property. You can draw an arrow but I dont think its worth the hassle.

I am writing code for generating my report in PDF using MigraDoc. I have downloaded the code from PDFSharp site. The following has 3 functions DefineStyles(), CreatePage(), FillContent(). I made changes in function CreatePage(), FillContent(); But when I am running the program I am getting error saying
Argument out of Exception:
Specified argument was out of the range of valid values.
In the CreatePage() I added 2 rows and 2 columns to a table. And in the FillContent() function I read my XML file. But I am unable to find where I am crossing my index range.
SOLVED
The problem is when I am setting the table.SetEdge(...). I am accessing the columns that I have not created.
Thank u all .. :)
At this step I was setting the rows that are not yet created.
this.table.SetEdge(0, 0, 2, 3, Edge.Box, BorderStyle.Single, 0.75, Color.Empty);
Instead of 3 which are the number of rows I should use 2.
I am displaying data in asp.net chart control. Using a 3d bar chart. I am showing the values next to the bars. (seriesCount.IsValueShownAsLabel = true;). The chart control is rendering the value label still on top of the bar and is making the value hard to read. I am trying to position this label to the right but so far I've found no way to do it. I've also tried enabling Smart labels hoping and putting a marker on the bar to push the value away but I haven't been successful. Any suggestions are appreciated.
Sample code:
Chart chartSubjects = new Chart();
chartSubjects.Width = Unit.Pixel(800);
chartSubjects.Height = Unit.Pixel(300);
chartSubjects.AntiAliasing = AntiAliasingStyles.All;
Series seriesCount = new Series("subjectsCountSeries");
seriesCount.YValueType = ChartValueType.Int32;
seriesCount.ChartType = SeriesChartType.Bar;
seriesCount.IsValueShownAsLabel = true;
seriesCount.ChartArea = "subjectsCountArea";
chartSubjects.Series.Add(seriesCount);
ChartArea areaCount = new ChartArea("subjectsCountArea");
LabelStyle yAxisStyle = new LabelStyle();
yAxisStyle.ForeColor = System.Drawing.ColorTranslator.FromHtml("#444444");
yAxisStyle.Font = new System.Drawing.Font("Arial", 11, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Pixel);
areaCount.AxisY.LabelStyle = yAxisStyle;
areaCount.AxisY.IsLabelAutoFit = false;
areaCount.Position.Width = 50;
areaCount.Position.Height = 100;
areaCount.Position.X = 0;
areaCount.Position.Y = 0;
areaCount.Area3DStyle.Enable3D = true;
areaCount.Area3DStyle.LightStyle = LightStyle.Realistic;
areaCount.Area3DStyle.WallWidth = 4;
areaCount.Area3DStyle.Inclination = 10;
areaCount.Area3DStyle.Perspective = 10;
areaCount.Area3DStyle.Rotation = 20;
areaCount.Area3DStyle.PointDepth = 90;
chartSubjects.ChartAreas.Add(areaCount);
int[] pointsToAdd = new int[] { 1434, 712, 601, 204, 173, 168, 64, 35, 22, 8, 2 };
foreach (int point in pointsToAdd)
{
DataPoint dataPoint = new DataPoint();
dataPoint.SetValueY(point);
seriesCount.Points.Add(dataPoint);
}
Is this what you are looking for?
<asp:Series Name="Series1" ChartType="Bar"
CustomProperties="BarLabelStyle=Right" IsValueShownAsLabel="True"
Palette="EarthTones" XValueMember="xvalue" YValueMembers="yvalue">
</asp:Series>
CustomProperties="BarLabelStyle=Right" did it for me.
In your case I'd use:
chartSubjects.Series["seriesCount"]["LabelStyle"] = "Right";
