A simple Zoom on the X-Axis??

Hi We are using TeeChart version 3.5.3187.15585 Ive spent some time searching the forums for an example of how to do a simple zoom IN on the horizontal axis only. The vertical axis should not be zoomed. Is it possible to do this. Simple example. If the chart has 100 points starting from x=1 to x=100...

Re: Why do I only have 2 labels on left axis?

Hi Christopher

We are using TeeChart version 3.5.3187.15585 and C#.NET

Bizarrely we found if the exponent was too small it didn't draw the labels. We have it working fine now by changing the units which allowed us to reduce the exponent.

Re: Why do I only have 2 labels on left axis?

Hi Christopher Apparently it works fine when the exponent is -10 or less. However for -10,-11, 12 etc the labels aren't displayed. We've got round this by labelling the axis uJ instead of J. So weve effectively multiplied the values by 1 million and everything is ok. This issue may have been fixed i...

Re: Why do I only have 2 labels on left axis?

I wrote a test program and the following worked.

spectrumChart.Axes.Left.Labels.Exponent = true;
spectrumChart.Axes.Left.Labels.ValueFormat = "#.0 \"x10\" E+0";


Will test on our own project later.

Re: Why do I only have 2 labels on left axis?

Anyone with any ideas?

It seems like when you do;

myChart.Axes.Left.Labels.Exponent = true


The labels don't display. However if

myChart.Axes.Left.Labels.Exponent = false


then the labels do show but they are all zero because the values are so tiny.

From software can I select Export tab in chart editor?

Hi Currently we display the teechart editor when the user clicks on a chart. We use this code; Steema.TeeChart.Editor editor1 = new Steema.TeeChart.Editor(myChart); editor1.ShowModal(); This displays the Teechart editor with the "Chart" tab set to display by default. Is there a way to have the "Expo...

Why do I only have 2 labels on left axis?

Hi Ive set the following to define the left axis; myChart.Axes.Left.Labels.Exponent = true; myChart.Axes.Left.Labels.ValueFormat = "00e-0"; However when I plot a curve on the line only 2 labels are shown; 0 and 1.3(e-13) despite the fact my plot extend from e-15 to e-18 Do I need to set some value t...

Re: My Labels OverLap

Thanks Sandra. Actually Ive just noticed that in the TeeChart editor there is a checkbox which helps. Click Chart tab, then the Axes tab then select "Bottom Axes", then the Scales tab and check/uncheck the "Inverted" check box. This reverses the chart and draws the correct labels in the Bottom axis....

How do I set Labels Increment

Hi there This is a very similar question to my previous one. I am adding labels programmatically using C#.Net (see below) However when I zoom-in I don't see any labels How do I make my custom labels behave in a similar way to the default labels? ie. when you zoom-in you see labels at the new scale T...

My Labels OverLap

Hi there I am adding a line to a Chart. Usually this is straightforward however, in this case I need to have the line plotted with the highest X-value at the left most position on the X-Axis and the lowest X-value at the furthest point on the X-axis. ie. I need to reverse the labels. As far as Im aw...

Re: Why does the chart legend update every point?

Note Ive set the legend as this;

ourChart.Legend.LegendStyle = Steema.TeeChart.LegendStyles.Series;


So I would expect to get one entry for each series (line) added to the chart.
Not one entry for each point added to the chart as we get currently.

Why does the chart legend update every point?

Hi Not sure why this has suddenly started happening with our charts but when a point is added , lets say (10,130) then the number 130 appears in the legend of the chart. Then we add another point, say 20, 156), and the number 156 appears as well. So every point that is added the legend gets bigger a...

How do I read first series selected from legend checkboxes?

Hi

If there are say 10 series on the chart and there is checkboxes on the chart legend to allow selection of each one how do I get the first selected series (ie. the first series with the checkbox checked).We are using TeeChart version 3.5.3187.15585 and C#.NET

Thanks
