ScatterCtrl Demo
Scatter series in GUI applications
ScatterCtrl_Demo package does a visual review of ScatterCtrl class features.
Here there are some screenshots:
General view
Demo program contains control samples in different tabs.
All of them have different export possibilities like:
Print Preview
Export as PNG
Export as JPEG
Export as EMF
Copy to Clipboard
Scatter controls lets to export in more formats.
In addition there are different painting modes to let either smoother or faster plots.
|
|
|
|
Basic Test
Scatter lets to show different data series changing various parameters like color, line width, dot style.
|
|
|
|
Functions
Using PlotFunction() it is possible to directly draw functions instead of just stored data.
|
|
|
|
Parametric Functions
While PlotFunction() functions just return the vertical axis, PlotParaFunction() functions return the XY coordinates of every point.
This options lets full freedom inserting XY series.
|
|
|
|
Formatting
ScatterDraw/ScatterCtrl lets to insert X and Y labels, XY scaling and range, point format and size and standard or user defined axis labels formating.
In addition SetMouseHandling(true) lets to use the mouse to zoom and move the graphs in X axis.
|
|
|
|
Dynamic
ScatterCtrl is not an static control and easily lets to include dynamic series handling.
|
|
|
|
Log
Versatile axis scaling and labeling through cbModifFormatX and cbModifFormatY lets to include not only time and date axis but also logarithmic ones.
|
|
|
|
Operations
Series dynamic handling is easy. This demo lets the user to add and remove series.
|
|
|
|
Secondary Y axis
It is possible to add a secondary right side vertical Y axis and scale data series to it.
In addition SetMouseHandling(true, true) lets to use the mouse to zoom and move the graphs in X and Y axis.
|
|
|
|
Big datasets
Big datasets are hard to handle. However there are two functions that speed up dramatically ScatterDraw/ScatterCtrl response in X axis sequential datasets like time series:
SetSequentialX: Indicates that the data has been sequentially inserted following X axis
SetFastViewX: Indicates that it will be viewed a point per horizontal pixel. This point will be the average of all data that is in that pixel
|
|
|
|
User graph
User can set custom graph types and marks.
