Re: TColorGrid Cursor Tracking

Is there public access to your bug tracking tool? Will I be notified when a fix is available?

Re: TColorGrid Cursor Tracking

Ok. Using the web link, I got a file size too big error. I included the Debug folder in the zip file. I'll remove that and try again.

Re: TColorGrid Cursor Tracking

Yes, I did. And I watched in Task Manager as the Network Activity for outgoing messages increased, and then went idle again. Then the screen refreshed, wiping out my reply. So I typed it in again, and hit submit.
Trying again...

Re: TColorGrid Cursor Tracking

Narcis, I've uploaded a zip file with all of the project files. In the mean time, I've been experimenting with the problem. Since it seemed to be related to the Pen.Visible property, I set that to True, and changed the PenStyle to psClear. That helped. But I ran into the same problem when I had to c...

Re: TColorGrid Cursor Tracking

Narcis, Before downloading a new version of the software, I wanted to be sure I could create a small project that reproduces the problem. It turns out that the problem happens when I turn the Pen off for the Grid. Below is some code, and the form file to recreate the problem. As shown below, the cod...

Re: TColorGrid Cursor Tracking

Narcis, Thanks for the reply. It appears that Clicked() is working the same as GetCursorValueIndex(). I still get -1 for a majority of the points on the grid. The grid contains about 230K points. I am getting values for points where the X value is less than 0.735. The points were added with the X va...

TColorGrid Cursor Tracking

I have a chart with a TColorGridSeries. I'd like to be able to display x, y, z values on the screen as the mouse cursor moves about the chart. I've tried using the Mark Tips Tool, but got no results. I've also tried writing a handler for the MouseMove event of the chart. In the handler, I call Serie...

Re: GetCursorValueIndex throwing EOSError

Yes. I can confirm that by not selecting the option "On resume, show Welcome screen", the problem does not appear.
Is there some other work around, other than catching the exception?

GetCursorValueIndex throwing EOSError

I'm calling GetCursorValueIndex inside the GetMarkText handler for a series that is updating fairly frequently (about 10 times/second). It appears that whenever the screen saver starts up, the call to GetCursorValueIndex is throwing an EOSError exception. The text of the exception is "A call to an O...

Waterfall Performance Hints?

I have a TWaterFallSeries with over 330,000 points. I have already turned on FastBrush. Do you have any other performance hints to help. I have a TTeeCommander on the chart, and the refresh rate is painfully slow when changing depth, rotation, etc.

Control Depth from Program

Which setting to I modify in my code to have the same effect as the Depth tool in the TeeCommander?
For example, I'd like to have the depth set to 10%. But I'd like to do it from code, not by the user's manipulation of the TeeCommander button.

Re: TeeUseMouseWheel Scroll Distance

When you add that functionality, you may also want to consider changing the value, or having a separate value, for when the vertical axis is in logarithmic mode. That's the reason for my original inquiry. The default behavior doesn't work too well on a logarithmic scale.

MouseWheel Scrolling doesn't trigger OnScroll

The subject says it all. The same is probably true if the AxisScroll or AxisArrows tools are used. All three behave differently than manually panning with the right mouse button. After panning around with the right mouse button, UndoZoom restores the chart to it's "original" axis values. Using the M...

Scope of TCursorTool grabbing mouse cursor

I have a TCursorTool on a chart. It's Style is both. The horizontal and vertical sizes are both set to 10. This makes the cursor appear as a cross-hair. When the mouse cursor is anywhere on the chart, whenever it crosses the projection of the cursor lines, the mouse pointer changes to indicate that ...
