Axis labels on bottom axis jammed for horizontal bar

ESRI · Post by **ESRI** » Wed Oct 05, 2005 12:22 am

If we use, for example, values 0,1,2,3,4,5,6 to build a horizontal bar, automatic labels for the bottom axis overlap for most sizes of the window. If we use 1e-5,2e-5,3e-5,4e-5,5e-5,6e-5,7e-5 it formats and places labels fine.

Hi Alex,

I'm not able to reproduce it here using the code below:

Code: Select all

    With TChart1.Series(0)
        For i = 0 To 6
            .Add i, "", clTeeColor
        Next
    End With

Does this code works for you? Please feel free to modify it so that we can reproduce the proble here.

Narcís,
Here is a c# code which exports BMP with jammed labels.

using System;
using TeeChart;
namespace tee_test
{
/// <summary>
/// Summary description for Class1.
/// </summary>
class Class1
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main(string[] args)
{
ITChart pChart = new TChartClass();
pChart.ClearChart();
int idx = pChart.AddSeries(ESeriesClass.scHorizBar);
pChart.Aspect.View3D = false;
pChart.Legend.Visible = false;
pChart.Header.Visible = false;

ISeries pSeries = pChart.Series(idx);
pSeries.Marks.Visible = false;

for (int i = 0; i < 7; i++)
pSeries.Add(i, null, 0xffffff);

IBMPExport pBMP = pChart.Export.asBMP;
pBMP.Height = 250;
pBMP.Width = 600;
pBMP.SaveToFile("c:\\tee_testJam.bmp");
}
}
}

After additional testing i see that line

pSeries.Marks.Visible = false;

makes the difference.
If commented there is no label jam!

So the question is why

pSeries.Marks.Visible = false;

makes the label jam?

Hi Alex,

Yes, I've been able to reproduce that and added the issue (TV52011014) to our defect list to be fixed for future releases. I've found that another workaround is setting pChart.Axis.Bottom.Labels.Style = EAxisLabelStyle.talMark as shown here:

Code: Select all

		static void Main() 
		{
			ITChart pChart = new TChartClass(); 
			pChart.ClearChart(); 
			int idx = pChart.AddSeries(ESeriesClass.scHorizBar); 
			pChart.Aspect.View3D = false; 
			pChart.Legend.Visible = false; 
			pChart.Header.Visible = false; 

			ISeries pSeries = pChart.Series(idx); 
			pSeries.Marks.Visible = false; 

			for (int i = 0; i < 7; i++) 
				pSeries.Add(i, null, 0xffffff); 

			pChart.Axis.Bottom.Labels.Style = EAxisLabelStyle.talMark;

			IBMPExport pBMP = pChart.Export.asBMP; 
			pBMP.Height = 250; 
			pBMP.Width = 600; 
			pBMP.SaveToFile("c:\\tee_testJam.bmp"); 
		}

Another solution is increasing bottom axis increment:

Code: Select all

pChart.Axis.Bottom.Increment=0.4;
