Re: Zooming-in on my scatter graph sometimes shows diddly squat
Thanks Narcis I will try that. Ive been playing about with the TeeChart editor and I can improve the display when I set the border transparency of the Points to 50%. However I dont know how to do this in code? I tried something like: pts.Pointer.Border.Transparency = 50; but of course this doesn't e...

Re: Zooming-in on my scatter graph sometimes shows diddly squat
Sandra yes you have circled the correct area.
I tried making the points smaller but the chart doesn't look very good. Also expanding the chart doesn't help much.
Im going to try and play around with the chart editor settings and see if I can make the chart look better. Thanks for your help.

Re: Zooming-in on my scatter graph sometimes shows diddly squat
Sandra thanks. Yes that code works OK. I think Ive worked out why there was a problem. Its because my chart data plotted several points at the same location. If I ensure no 2 points are the same then the graph draws OK and I can zoom into any area. However the chart doesn't look quite right. There i...

Re: Zooming-in on my scatter graph sometimes shows diddly squat
Hi Sorry for the delay in getting back (was sidetracked to something else temporarily). Its a bit difficult for me to send the project because its so large. I basically create the chart by reading the x and y coords into 2 arrays. I then call drawGraph(x,y) which draws the chart. ie. public void dra...

Re: Zooming-in on my scatter graph sometimes shows diddly squat
The source for the executeable is very simple. Here it is. Its in C#.Net using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace TeeChartTest10 { public partial c...

Re: Zooming-in on my scatter graph sometimes shows diddly squat
Thanks. Ive uploaded an executeable and a chart for for you to look at. Its compressed. Let me know if there are any problems. You need to add TeeChart.dll to make it run. I tried uploading the project including the TeeChart.dll but the file was too big. Try zooming-in on the concentrated circular s...

Zooming-in on my scatter graph sometimes shows diddly squat
Hi I have created a scatter graph using TeeChart NET v3 There are quite a lot of points, typically around 50,000. They are in a single "Points" series When I zoom-in using the mouse (dragging a rectangle) it sometimes shows a blank. ie. zero points. Ive noticed when I zoom in on the right side of th...

Re: Changing Legend Symbol Width in Code?
Sandra
Thanks that works. Ive discovered I need to set the symbol width AFTER adding a series to the chart.

Re: Is there a "Change" Flag for Teechart?
Im getting it to work correctly ALL times if I do the following before calling the editor. Dont know if something is being cleared somewhere but it works
byte[] tmpbuffer1, tmpbuffer2;
tmpbuffer1 = ExportToByte(tChart1);
tmpbuffer2 = ExportToByte(tChart1);
byte[] tmpbuffer1, tmpbuffer2;
tmpbuffer1 = ExportToByte(tChart1);
tmpbuffer2 = ExportToByte(tChart1);

Re: Is there a "Change" Flag for Teechart?
Yeray have you tested this example? It seems to work almost every time when the editor is displayed and closed. ie. it correctly identifies when changes have been made and when no changes have been made. However the exception is the very first time the editor is displayed and closed. In this case it...

Re: Is there a "Change" Flag for Teechart?
Hi Maybe Ive not explained this well enough. Im developing a windows application using C#.NET. The application contains a form that includes a TChart. I have provided an option that lets the user use the Tchart editor. As most of you will know this allows the user to change things such as titles, le...

Is there a "Change" Flag for Teechart?
Hello Support
Id like to be able to prompt the user if he/she would like to save changes before closing the chart.
Is there a flag I can check that will tell me if the user has made any changes using the chart editor?
regards
