I've made some headway with using:

Code

public override void Plot()

Is it possible to pass variables into this function from my main program?

The answer is YES! Although indirectly.

The variables created in main function declared globally are available to that function.

Also, if you have this in a separate study as I do, .... you can first capture into the main body of script any variables from OTHER studies, and then those variables are available to the void plot() function.

Woot!

glad...ur getting interest.
about aligning text in graphics in different lines...there are string formats and you can get the hieght of text to be displayed to offset next line.

yes can have globals to transport values...but recently i stuck with graphics plot.....could not retain values
outside the Plot scope as opposite to other methods. It was very frustrating excercise to get values derived
inside graphics plot to outside. Hope some more experienced coder help me out.

Code

 
public override void Plot(Graphics graphics,Rectangle bounds,double min,double max)
{
 
mymin = min;                    // mymin Global variable.
Print(mymin.ToString());   // works only if remains as long as in Plot. Losses value
}                                      // outside the plot.

If you wanted to add the textbrush as a user input so that you could change the colors, how do you go about doing that?

If you wanted to add the textbrush as a user input so that you could change the colors, how do you go about doing that?

this is simple and similar to other variables. Look following changes should be made in script.

1) Declare your text brush without initialisation and add another variable for color.

Code

 
#region Variables
.........................
private  System.Drawing.Brush   textbrush;    // no initialization of Brush
private  Color   textcolor;                                 // variable for color.
..........................
#endregion

2) Initialize TextBrush where u need and dispose after use.

Code

 
public override void Plot(Graphics graphics, Rectangle bounds, double min, double max)
{
............................
textbrush = new SolidBrush(textcolor);        // initialize here
.......................
.......................
.......................
textbrush.Dispose();                                    // dispose after use.
 }

3) Make provision for this in Properties...so that it could be shown for input.( Important)

Code

 
#region Properties
[Description("Select Text Color")]
[Category("Colors")]
[Gui.Design.DisplayName("Text Color")]
public Color Textcolor
{
get { return textcolor; }
set { textcolor = value; }
}
#endregion

and you are done...
