Hi,
i'm using a FastLine Serie and i need to visualize 32 bit values on left axis from 0 to 0xFFFFFFFF. The problem is that the serie works with double values and a value higher than 0x7FFFFFFF is displayed as a negative. I only need to display positive values (from a minimum of 0 to a max of 0xFFFFFFFF). Is there a way to solve my problem?

Hello,

You could intercept the labels at OnGetAxisLabel event and modify them to fit your needs.

Thank you for your answer, that sure is useful, but that doesn't solve my problem.
I'm sorry to resume this post, i will try to be explain better my problem with an example:

The image shows my problem, the axis are in hexadecimal format, but my problem are not the axis, but the values of the Chart (TFastLine). So the value at 0x90 (on Bottom-Axis where is the cursor) is 0x8991B183 (Left-Axis) and is not shown correctly on the Chart because it is greater than 0x80000000. Or to be more accurate, the value is not visible but is been drawn as a negative, but what i need is to draw it as a positive, and thus consequently draw all values greater than 0x80000000 as positives! In my application i don't need to view negative values.

I think of a workaround to manipulate values before drawing them but seems a pain. I thought there should be a simpler way to do it.

Thanks

Hello,

I'm sorry for the delay with this reply, we'd missed the post. To help us along, could you send us a small code sample or project that reproduces the problem; it will help us debug it and offer up possible solutions. You can send it to info@steema.com
