zgrid: grid preferences not applied with default.set

[BenB]

Hi,

It's a small detail, but I noticed that the grid display preferences are ignored when the preferences are applied automatically through default.set at the creation of a new zgrid plot. I have to click "get preferences" and select default.set again to have the grid appear on the plot!

Ben,
Assuming you're still talking about the Add-In ZGrid command, the grid lines are turned off by the Add-In. Currently (with all of the AddIn commands and any other program that produces a graph with DPlot_Plot or a similar function) DPlot first processes default.set if it exists, then processes any commands sent from the caller... and I don't think I'd want to do anything different with this.

I'll give some thought to whether the AddIn should be forcing several settings. Off the top of my head I think it will probably stay as is... but I might also talk myself out of that. If you're interested you can change the Add-In yourself so that the grid will be drawn with your default preferences. See "Editing the Add-In" here: http://www.dplot.com/help/index.htm?helpid_addin.htm. Find the ZGrid subroutine, then this line:

Code: Select all

    cmds = cmds & "[Contour3D(0)][ContourGrid(0)]"

and delete [ContourGrid(0)]:

Code: Select all

    cmds = cmds & "[Contour3D(0)]"

Hi Dave,

I did the modification you suggested, and it does display the grid now, but not in the right color!

Basically the grid appears gray, which I think is the Dplot default value, but in my default.set it is saved as black... Any idea of how I can force it to use the value in my default.set file? I tried playing with the commands in the Zgrid subroutine but didn't succeed so far.

Thanks in advance!

Unfortunately the color is forced to light gray within dplot.exe when the graph is first created (after default.set has been processed). Off the top of my head I can't think of a good reason to do this, and I'll probably change it in the next release.

You can force the color to black by modifying the Add-In again, this time adding a Color command:

[Color(0,0,0,0)]

The first 0 is the index of the item you want to change the color of; 0=grid lines. The next three parameters are r,g,b values 0-255.

Hi Dave,

That'll do it!

Thanks for your prompt answer,
Ben
