Hi All,
I'm currently trying to plot a list of vectors on a 2D chart. What I mean by 'vectors', is just a simple lines which start on an specific X-Y coordinate and ends on another one.
For this purposes I was trying to use the composite chart, specifically as a scatterChart, where each vector would be a single XYSeries object containing 2 XYDatapoints (start and end)
However, this proves somewhat troublesome, as each vector can vary in the following ways:
- Different lengths (can easily be accomplished by changing the 'ending' XYData point
- Different line styles (dashed, solid)
- Different colors
- Different symbols (each vector has just 1 symbol at the start point, but not the end point)
- Some vectors have a label next to it
I found that the LineAppearance class addresses most of these variants altogether; but I can't seem to find a way to apply a LineAppearance to a single XYseries in an scatterchart, so the workaround I found is to create several ScatterChartAppearance 's with all the format combinations I'll be using, and assigning a series to the scatterchartappearance; but that seems way too excessive.
So, my question would be, is there a way to customize the items I described above in a per-XYSeries basis? Or is there a better type of chart / way to approach this issue?
Also, what's the difference between scatterChart and scatterLineChart, given that the former has a ConnectWithLines property?
Thanks,
- Nicolas.
Hello,
I am just checking about the progress of this issue. Let me know If you need our further assistance on this matter ?
Thank you for using Infragistics Components.
Thanks!, it was just what I was looking for.
However, I wanted to ask you another question: to clean up the chart, is there a way to offset the labels that gets printed right on top of the start / end node, so as to make it more readable?
Thanks again,
What you could do is to set Horizontal and Vertical alignment of ChartTextApperance. So you could use following code in my sample
ultraChart1.ScatterChart.ChartText.Add(new ChartTextAppearance() { ChartTextFont = new System.Drawing.Font("Arial", 7F),
ClipText = false,
Column = -2,
Row = -2,
ItemFormatString = "<ITEM_LABEL>",
HorizontalAlign = StringAlignment.Far,// set horizontal alignment
VerticalAlign = StringAlignment.Far,//set vertical alignment
FontColor = Color.Black,
Visible = true });
I hope that this will helps you.
Thanks again; this will do for now.
