This does not appear to set the bar width the way we want, but setting histseries.custombarwidth:=x comes closer. what we cannot find is the units for the custombarwidth. For exzmple, if we have 10 bars and want to show them spread out across min,max for the series, how do we set this so the bars wo...

how do we set the width of the bars in a bar chart?

we are still having an issue,I think, with the smoothiong series. The smoothed series looks much like the original. Very little it may be the setings. We use factor=10 and our images. we also note that if we set intepolate=true, the progarm crashes as the interpolate method call. I cam post an image...

we are trying to smooth a series[profile series] and the series does not show up. Heres our code Procedure Tform1.DrawProfile4; VAR profilenode:TstListNode; min,max,mm:Integer; Tfunctiona:Tsmoothingfunction; BEGIN profileseries.clear; smoothseries.clear; profchart.bottomaxis.setminmax(profminfld.asI...

Thanks- We redid it as below and the strange thing is we have to clic k on draw twice to get series 2 display. Click #1 shows source serties 1, while the second clicks causes both 1 and 2 to show. ********************************************************** Procedure Tform1.draw; var Tfunctiona:Tsmoot...

we made up a very simple program to use the smoothing function which has a method called draw. when we "draw", we get a memory access error at the setfunction line. The two series[Series1,2] are added in the chart editor. code is below: It compiles fine **********************************************...

Thanks Mark- We went into Function_smoothing and we understand what it said. I think we need a little more help, but heres what we have- Assume the series we want to smooth is Series1 and the smoothing function is TeeFunction1 and the Series1 is populated. Then, it looks what we want do is: tempseri...

I agree with you completely. They should have more support here. Since
we are in the signal processing business, we would be interested in
support not only for the usual interpolation, but one with
the usual sp windowing functions to miniomize aliasing.

we have looked all over and cannot find much on spline cubuc. Could
you supply us with a few lines of code showing how to
implement spline cubic, with factor=4,interpolatrion=true?.

Thannks,

we have a chart where we set
allowzoom:=True and
zoomdirection=horizontal in the chart editor. then,
\when we aoom as in chart.zoompercent(125), both axes zoom.
How can we restrict zoom to horiz axis?

Thanks,

Jennifer

Thanks very much-Sometimes I wonder how we can be so obtuse aropund here. Probably form practice:-)

We are using Teechart VI and Delphi V and have a problem using functions. we made a simple example[below]. What happens is that when we compile, the compiler says the calcuilate method cannot be found. Thanks, Jennifer ********************************************************** unit Unit1; interface ...

Thanks-

We ened up generating another series and loaded it from the
poarent series and that worked fine. Not as elegant, but works. This
is the week to tackle functions.

I miust have mistyped the code to you-Sorry. In any event, we took the "2" out and the result is the same. The deriv plot ios about ao 10 units left of series 1. Here is the code: ******************************************************* Procedure Tform1.drawderiv_2; var Indx,N:Integer; valx:Double; B...

we are trying to generate a series showing the derivative of a plot. The original seris is called lineseries, and the derivative series is called deriv series. we are apporximating the deirvative at each point as one-half the difference of point[n+1] and point[n-1] which is good enough for what we n...
