Take a look at the screenshot: there are a few labels on both axis even though there is no related chart points. Can i configure chart control to show labels only when there is some data on chart (see second picture)?

If you want to customize the label with a specific axis value then you should handle the ChartControl.CustomDrawAxisLabel event. Please refer to the sample code snippet in the CustomDrawAxisLabel documentation article.
private void chartControl1_CustomDrawAxisLabel(object sender, CustomDrawAxisLabelEventArgs e)
{
AxisBase axis = e.Item.Axis;
if (axis is AxisY || axis is AxisY3D || axis is RadarAxisY)
{
//Put your condition at below two lines..
double axisValue = (double)e.Item.AxisValue;
if (axisValue == 0)
{
e.Item.Text = string.Empty;
}
}
}

I have a scatterplot that I would like to fit into an existing view:
scatterchart("Test", NumberAxis(), NumberAxis()) {
}
But I would like to get rid of the title at the top to centre the scatterplot in its view.
I have tried to set the title to an empty string but to no avail:
scatterchart("", NumberAxis(), NumberAxis()) {
// I'm looking for a method like this:
title.isVisible(false)
}
My goal is to get rid of that empty space at the top of the chart for a uniform look.
I'm not even sure what the correct way would be in JavaFx. Let me know if I'm on the right track, cheers!
Set the title to null:
scatterchart(null, NumberAxis(), NumberAxis())
Alternatively:
scatterchart(x = NumberAxis(), y = NumberAxis())
Now that we have Image plots capability in ILNumerics, I am replacing all my code to use ImageSc plots inplace of surface plots.
For surface plots, we can specify X and Y scale values in the form of grid. Is there any way to modify the index based scale values for image plots without overwriting TickCreationFunction?
you could place the plot inside a group and use the group to translate the plot inside the plot cube:
private void ilPanel1_Load(object sender, EventArgs e) {
ilPanel1.Scene.Add(new ILPlotCube(twoDMode: false) {
new ILGroup(translate: new Vector3(-5,10,100)) {
new ILImageSCPlot(ILSpecialData.sincf(10,20))
}
});
}
This would work with any plot object - not only ImageSC.
I'm drawing a line chart with javafx categoryaxis. e.g. I have 100 points on the plot. As such, all of my tick labels are squished together, resulting in 100 bunched-up ellipses. All I want to do is render every tenth label. I've looked through the documentation but there doesn't seem to be any way to turn individual tick labels visible or invisible, or how to change the setting of the tick unit on a CategoryAxis.
or I have to redraw xAxis?
just got an idea, add number of invisible char into the categoryaxis, so that each xaxis is still 'unique'
if (i%5 == 0)
str = DateFormat.getDateInstance(DateFormat.DEFAULT).format(date);
else {
str = invisible;
invisible += (char)29;
}
By default, minimum level of ASP.NET chart control is 0, I want to set this level to -1. So that 0 value on y-axis can be shown correctly...
This should work.
var chart = new Chart();
//
// Code to define chart areas etc...
//
chart.ChartAreas[0].AxisY.Minimum = -1;
I have a column chart that uses a label function to format the vertical axis. I added a button and want the axis (or chart) to redraw when the button is clicked. Right now, the chart axis renders OK only when initially added to the view state.
I have a function that sets various properties after the chart is initially created. In there, I have tried all these:
myChart.verticalAxis.dataChanged();
myChart.validateNow();
myChart.validateDisplayList();
myChart.validateProperties();
myChart.invalidateDisplayList();
myChart.invalidateProperties();
But they do not change the axis formatting. How can I do this?
The MXML code for the axis is:
< mx:LinearAxis id="verticalAxis" labelFunction="vAxisFormat"/>
The label function is:
private function vAxisFormat(labelValue:Number, previousValue:Object, axis:IAxis):String {
axis.getLabelEstimate();
if (_scale == 1){
return currencyFormatter.format(labelValue/_scale);
}else {
return numberFormatter.format(labelValue/_scale);
}
}
Try updating the data provider. This redraws the graph, so all the components.
Example:
ArrayCollection
arr.refresh ();
XML
char.dataprovider = xmlData
regars
