I'm having an issue with PHPExcel that it is not PHPExcel's fault. In a graph, the values being presented are very large, so since the default setting for the axis options for Minimum is Automatic, Excel is deciding to use a minimum value for the Y axis of 156,000. The issue can be "Fixed" in Excel by going into the Axis format option and setting a Fixed value of 0 for the minimum of that axis.
So I've been trying to figure out if you can set this option from within PHPExcel, but can't figure out if it's even possible.
So can you change the Chart Axis format options from within PHPExcel, and if so... how?
Thanks,
It's an option that isn't yet available with PHPExcel
It shall be possible now with this fix: https://github.com/PHPOffice/PHPExcel/commit/1a237573f9127a02388f4e306732122b39d1ea49
Usage example (100 is the max. value):
$axis = new PHPExcel_Chart_Axis();
$axis->setAxisOptionsProperties('nextTo', null, null, null, null, null, null, 100);
$chart = new PHPExcel_Chart('chart' . $locTL, $title, $legend, $pa, true, 0, NULL, NULL, $axis);
I have tested only max limit but I believe it shall function properly for min limit as well.

I am adding data to scatter series like below , how do we receive the custom parameter value I add here
series.add({
x: 0,
y: 22,
color: ColorRGBA(255, 0, 0),
size: 10,
rotation: 45,
value: "custom message",
});
From the above series how do I extract the value "custom message" .. basically is there anyway to get it ? so I can to use it in table formatter like below .
series.setCursorResultTableFormatter((builder, series, xValue, yValue,value) => {
return builder.addRow(value).addRow(series.getValue());
});
Also another doubt is can we change shape of series dynamically like we change color and size ?
With v.3.1 this kind of logic is not supplied out of the box.
To implement it you'd need to add some kind of custom logic which finds your custom data based on the X and Y information.
In next release, v.3.2 we'll add an extra parameter to cursor result table formatters, so you can use it like follows:
series.setCursorResultTableFormatter((builder, series, x, y, dataPoint) => {
// `dataPoint` has all same information as user supplied, size, rotation, value or anything.
return builder.addRow(x).addRow(y).addRow(dataPoint.value);
});
Please note that these custom properties (size, rotation, value, etc.) will only be included when cursor interpolation is disabled.
At this time v.3.2 is scheduled for late September, but this could change.
2nd question about changing shape of point series, we currently don't have active plans to change this, but when there is enough motivation it will be improved on.
I need to create a report that displays an empty ALV with 4 columns and that is editable (the user can input on the fields of the ALV).
The ALV is going to be used as an input for the user and the data is then going to be read from the ALV.
What would be the best approach for this?
When youre setting the fieldcatalog, you need to declare "editable". For example
wa_fieldcat-fieldname = 'REMARKS'.
wa_fieldcat-scrtext_m = 'Purchase Order'.
wa_fieldcat-col_pos = 1.
wa_fieldcat-outputlen = 10.
wa_fieldcat-editable = 'X'.
wa_fieldcat-key = 'X'.
APPEND wa_fieldcat TO it_fieldcat.
CLEAR wa_fieldcat.
Then you need to declare in your process after input(PAI) the check changed data of the alv.
alv->checked_changed_data
I want to hide the horizontal major/minor lines that appear on Graph2D Y-axis values of a scatter plot/timeline.
I have tried to make use of showMinorLines and showMajorLines without much success. The syntax am using is:
graph2d.setOptions({showMinorLines: false})
However, it generates an error that states:
Unknown option detected: "showMinorLines". Did you mean
"showMinorLabels"?
Problem value found at: options = { showMinorLines }
vis.js:23607 Errors have been found in the supplied options object.
Any help would be much appreciated?
Update: Attaching image.
Thanks for bringing this up. This is an fault in the documentation: in v4, this option has been renamed to get a more consistent API. You now have the following four related options:
{
showMinorLabels: true | false, // minor labels and lines on horizontal axis
showMajorLabels: true | false, // major labels and lines on horizontal axis
dataAxis: {
showMinorLabels: true | false, // minor labels and lines on vertical axis
showMajorLabels: true | false, // major labels and lines on vertical axis
}
}
We will fix the docs, sorry for the inconvenience.
I want to hide the datapoint label if the value of my datapoint is zero. I am trying the following field expression in visibility of series label property. It does not appear results as expected.
=IIf(Sum(Fields!RH_Col.Value, "DataSet2") = 0, false, true)
Your issue is with the Scope of your statement... You are checking the whole DataSet, but you should be checking the Category Group only, something like:
=IIf(Sum(Fields!RH_Col.Value, "Chart1_CategoryGroup1") = 0, false, true)
These names are typically auto-generated, so check the Category Group properties to get yours.
I have a chart with a DateTime axis as my horizontal and a Linear Axis for my vertical inside a Adobe Flex Line Chart. I want to use a Cartesian Data Canvas as a background element and draw custom set of background graphics mostly rectangles. When I have more than a single data point, the graphics work perfectly since they are supposed to span the width of the entire chart.
When I have only a single data point, however, I can't seem to get the rectangles to draw. Since I want my rectangles to span the entire width of the chart, I was thinking that I could get the x-coordinates from my axis, but this isn't working.
var canvasWidth:Number = chtCanvas.width;
var canvasHeight:Number = chtCanvas.height;
var minPt:Array;
var maxPt:Array;
var minPtDate:Date;
var maxPtDate:Date;
var minPtComplete:Point;
var maxPtComplete:Point;
// This works fine when there is more than 1 data point
minPt = chtCanvas.localToData(new Point(0, 0));
maxPt = chtCanvas.localToData(new Point(canvasWidth,canvasHeight));
//This does return a date object, but wont draw below
minPtDate = axisDate.minimum;
maxPtDate = axisDate.maximum;
//This returns NaN for the x
minPtComplete = chtCanvas.dataToLocal(minPtDate, axisSalary.minimum);
maxPtComplete = chtCanvas.dataToLocal(maxPtDate, axisSalary.maximum);
// Also tried this. Also returns NaN for the x value
//minPtComplete = chtCanvas.dataToLocal(axisDate.minimum, axisSalary.minumum);
//maxPtComplete = chtCanvas.dataToLocal(axisDate.maximum, axisSalary.maximum);
My actual drawing method is as follows:
// Tried this, works with points >2, does not draw with single data point
chtCanvas.drawRect(minPt[0], detail[i].MaxValue, maxPt[0], detail[i].MinValue);
//tried this, no effect with single point
//chtCanvas.drawRect(minPtDate, detail[i].MaxValue, maxPtDate, detail[i].MinValue);
// Tried this, no effect with single point
//chtCanvas.drawRect(minPtDate, minPt[1], maxPtDate, detail[i].MinValue);
// Tried this also
//chtCanvas.drawRect(minPtComplete.x, detail[i].MaxValue, maxPtComplete.x, detail[i].MinValue);
In this example, detail is an array collection of salary values and Im using the data value in the array to determine the vertical bounds of my rectangles.
I need to draw the rectangles the entire width of the chart (even when there is only a single data point). Thanks
Thanks to Heikki for his help. The following code works to use the axis values to draw on your Cartesian Data Canvas:
chtCanvas.drawRect(axisDate.minimum as Date, axisSalary.maximum, axisDate.maximum as Date, axisSalary.minimum);
Casting the values as Date really helped. The rest of the code used above is unecessary.
One thing to note, I was using a DateFormatter to format the date values from my data. What I didn't consider was that when using a DateTimeAxis, Flex will automatically add in extra dates to display on the axis. In my case, I was using a custom parse function to create MY points, but wasnt considering the points Flex was creating and also passing to my parse function (Therefore, they were not getting parsed correctly). Once I corrected this, the values laid out correctly in the case of multiple data points. I'm still having a bit of an issue with single data points and them not filling the chart entirely, but they are now drawing.
UPDATE:
Although there are signs of life, the minimum and maximum are still not drawing the entire width of the chart in some cases depending on the dataUnits and labelUnits combination.
UPDATE #2: SOLVED
Ok, so the axis does work as minimum/maximum values for the Cartesian Data Canvas but there is something important to remember. For a single point (and probably for multiple points as well, I just couldnt visually see the difference), when using a custom DateTimeAxis parse function such as what was in the Adobe Flex ASDoc tutorials:
private function axisDateParseFunction(item:String):Date
{
var inputDate:String = item;
inputDate = fmtDate.format(inputDate);
var newDate:Date = new Date();
if(inputDate)
{
var a:Array = inputDate.split('/');
newDate.fullYear = a[2];
newDate.month = a[0] - 1;
newDate.date = a[1];
newDate.hours = 0;
newDate.hoursUTC = 0;
newDate.minutes = 0;
newDate.minutesUTC = 0;
newDate.seconds = 0;
newDate.secondsUTC = 0;
newDate.milliseconds = 0;
newDate.millisecondsUTC = 0;
}
return newDate;
}
You MUST remember to set the UTC values as shown above also. Since the DateTimeAxis uses date AND time, when you create new Date objects, their time values also get set to the local system time. Remember to set those values to zero also or you will get points that dont exactly line up with your axis labels.
