Hi All I'm considering to upgrade from v7 to v8 primarily to improve my graphs with contour series. In the topic: http://www.teechart.net/support/viewtopic.php?t=4930 it was stated that this feature is likely to be implemented in v8. However I can not find it in the demo. Is this feature in v8? Rega...

Hi All

I have a real-time data aquistion application. I want to display a legend like:

Oxygen (13.5 mV)
Nitrogen (27.4 mV)
Test ( 9.5 mV)

Is there a simple way to ensure that the first "(" is aligned??

The legned also have checkboxes and symbols!

Hi Narcis I can not make your suggestion working. The code below (with one timer, one tchart and one points series) don't autoscale. The lower left axis is always -10 (the starting point) However, the solution is also a bit difficult for me to implement as the recording frequency of my points might ...

Hi All I have a real-time charting question. My users can select to display only part (e.g. the last 5 minutes) of a big point series. Is it possible to make the left axis autoscale only on the points shown, or do I have to manually search for minimum and maximum within the points shown on the axis?...

SOLVED:

The error was caused by an installation of 7.08 on top of a 7.06.

Solution remove both and reinstall 7.08

Hi All I have a quite strange problem. My application consist of a number of Tchart on different tabbed pages. When I change axis settings (i.e. min, max or title) at runtime the axis are not updated to the new values (allthough if I read the values these are correct!). If I copy the graph to a new ...

Hi All I have a problem when I print a chart. Within my application there are several chart. Most of these can be printed (using aChart->Print()) without problems. However, when I print a chart with a point series, a line series and an area series the print procedure raises an access violation. Any ...

Hi

The curvefitting fits normalised data. That is Y-MinY and X-MinX (In your case Y-10 and X-1). Re-inserting this into the fitted polynomial should yield the original equation.

Hi Pep This is excatly my original problem. I don't know how to calculate the RBG value manually. I looked at the www but could not find any code to do this. This was why I posted this question. Has anybody reference to some code that can calculate the RGB values between to colors?? Any help will be...

Hi Pep

As far as I can see these examples only includes a gradient of i.e. red. My problem is to produce a gradient or ramp between two different colors.

How do I produce i.e. 15 RGB values that ranges from green to yellow??

Any suggestions?

Hi All I have a small problem. My application has a graph with multiple line series. The number of series is unknown at design time. The users would like to have the series color ramp between two colors (i.e. Green to Yellow or Blue to Red). They would like to make the start and end colors user sele...
