User (Legacy) Posted February 7, 2003 Report Share Posted February 7, 2003 I have two charts: Top chart is a multiple line chart and the bottom part is bar chart. I put "Mouse Move" event on the top chart. When the mouse hoover on top of the chart. I draw a constant line on both charts. However, when I got a lot of data, the constant line would not draw at the same time. There's a slack of time when drawing the constant line. Is it a bug? or is there any property that I have to set?

Software FX Posted February 7, 2003 Report Share Posted February 7, 2003 Is it a vertical constant line ? these charts are not aligned in the X-Axis, the first chart has 10 points while the second has 16. The constant line value is being assigned to what ? I'm not clear if this is what you mean, are you talking about the amount of time it takes to draw ? how many points are we talking about ? the sample you attached has very few points. -- FP Software FX, Inc.

User (Legacy) Posted February 7, 2003 Author Report Share Posted February 7, 2003 I'm sorry. The sample is only a sample. I attached the current chart. Yeah, I'm talking about the amount of time, to draw the vertical constant line. I have 8 series with 100 data in it for the top chart. For the bottom chart, I only have 1 series with 100 data. When I scroll the mouse, the vertical constant line for the second chart, refreshed faster than the second line. So the line in the first chart seems left behind. Thanks for your help.

Software FX Posted February 7, 2003 Report Share Posted February 7, 2003 Well, this is normal as the first chart takes longer to draw, you may want to optimize your MouseMove code so that you don't change the constant value if it is the same, this way you will eliminate a lot of unnecessary re-drawing. Redrawing the chart in every mouse move is going to feel slow when you have this many points. -- FP Software FX, Inc. Link to comment Share on other sites More sharing options...
User (Legacy) Posted February 10, 2003 Author Report Share Posted February 10, 2003 Is there any way, I could show 50 data without having instert the data again.. since I've got 100 data already.. I think it would make the chart more faster.

Software FX Posted February 11, 2003 Report Share Posted February 11, 2003 No. However, there are settings that will improve the performance, check the section "Performance & Scalability" under the Internet Features in the "Samples & Resource Center) for tips. Also, a 100 point chart takes less than a second to draw, normally you would not even notice, the issue here is that you are repainting on EVERY mouse move. Did you implement the suggestion I gave you in my previous post ? -- FP Software FX, Inc. Link to comment Share on other sites More sharing options...
