This package contains 2 components:
|
|
|
|
TPlotFunctionPanel
|
|
Plots a function y=F(x) on a grid.
|
|
The function result is calculated with an event "OnCalcPlot". This
|
|
function is called for each X for which an Y must be calculated.
|
|
|
|
TPlotExpressionPanel
|
|
Plots a function y=F(x) on a grid.
|
|
The function result is calculated from the expression "Expression"
|
|
The fpexprpars unit is used to calculate the expression. The
|
|
"Identifiers" property of the parsers is exposed so the variables
|
|
and function definitions can be manipulated
|
|
|
|
Both components have the following properties:
|
|
|
|
Active : If set to false, only the grid is drawn.
|
|
|
|
PlotColor : Color of the plotted line
|
|
|
|
Caption : Caption of the graph
|
|
|
|
|
|
XAxis, YAxis: These control the appearance of the X and Y axis.
|
|
They have both the following properties:
|
|
Color : Axis color
|
|
TickColor : Color of the tick marks on the axis.
|
|
Ticks : Number of tick marks or distance between tick marks on the
|
|
axis.
|
|
TickSize : Length of the tick mark.
|
|
TickMode : Ticks is number of ticks or distance (in pixels) between ticks.
|
|
TickFont : Font for the tick labels
|
|
Caption : Caption of the axis.
|
|
Drawzero : Should the 0 line be drawn extra ?
|
|
Origin : Starting point (in X or Y) of the axis.
|
|
Interval : Interval over which will be drawn. The axis covers the
|
|
X or Y interval [Origin,Origin+Interval]
|
|
|
|
LegendInterval : The interval (in ticks) at which a legend for the tick
|
|
mark should be printed.
|
|
LegendFormat : Controls the formatting of the legend at the tick marks.
|
|
This should be a valid float formatting specifier (used in FormatFloat);
|
|
GridInterval : The number of ticks at which a grid line must be drawn.
|
|
GridColor : Color of the grid line.
