Topic: custom axis title position
Replies: 6
Views: 2867

Hello, One idea I stumbled across was to leave the bottomAxis and leftAxis alone, and create custom axes at the zero position of the data. I would only make the title of the left and bottom visible, and would associate the tickmarks and labels with the custom axes. That would give me the effect that...

custom axis title position

Hello, I have modified by chartAxis.positionPercent such that the axes are located at the 0,0 data point see below: http://www.denovosoftware.com/download/badaxis.jpg As you can see in the image, the axis titles are still located just below, and to the left of the axes. What I would like to do is pu...

Legend Order

Hello,

It seems that the legend items get drawn in the order of the seriesList. Is there a way to change the order in the legend. For instance, if I want to list the legend items alphabetically or something?

i.e.

series.showInLegend:=true;
series.LegendPos:=7;

something along those lines?

Extended pens are defined as part of the windows api. They allow you to have, for instance, dashed pens greater than 1 pixel wide.

However, the changes we had to compensate for were introduced around tchart 5 or so

Hi,

One of the things that we had trouble with is that tchart sometimes uses extended pens. Sometimes these are not supported by all devices. Do you know if your printers support these?

I think we are using TChart 7.03 but I will have to check.

The code that we use for this is very involved. I can try to save the chart to a .tee file at the appropriate place. Would that help you?

Hi, Good eye spotting the FACS data. The tchart code that actually calculates the size of the different parts of the plot (legend, titles etc) is so completely entangled with the code that draws the different parts that I despair of ever trying to do anything fancy in this regard. I thought I had it...

Hello, The isometric axis does not do exactly what I want. The isometric axis shrinks the area of the plot where the data is displayed. But it keeps large blank areas of the axes. I need to shrink the axes so that the axes are the same length, like the image shown below: http://www.denovosoftware.co...

square axes

Hello, I am trying to force the tchart to always have an equal length X and Y axis, irrespective of the size of the TChart.BoundsRect. I have tried the following change to Procedure TCustomAxisPanel.InternalDraw. (look for "// dn changes") Begin Old:=AutoRepaint; AutoRepaint:=False; CalcInvertedRota...

label overwrites titles

Hello, I have found that if you make the chart label too big, the label can overwrite the title. http://www.denovosoftware.com/download/labeloverwritestitle.jpg I have fixed the problem in chart.pas so that it works in my application. But it only takes into account the left axis, which is the only o...

As you mentioned, to create a histogram you have to define a bin width from your raw data.

Its quite straightforward to process the data yourself into bins, and then create a new binned series in TCHART.

Legend size seems incorrect

Hello, I have been experimenting with implementing different zooms. This is the case at 100% zoom http://www.denovosoftware.com/download/100.jpg I am changing the tchart to 35% zoom by changing the View3DOptions.fontZoom. I also change plot size to 35%. It seems to basically work okay (see below) ht...

Hi Narcis, I am trying to figure this out on my own, but I am confused how to apply what you said. All of those variables (IStartPos, iEndPos) change only after the chart has been drawn. I do not want to have to change the chart to figure out what the chartRect is, that defeats the purpose. I want t...
