 # Example (JKQTPlotter): Simple math image plot without use of central JKQTdatastore {#JKQTPlotterImagePlotNoDatastore}
-This project (see `./examples/simpletest_imageplot_nodatastore/`) simply creates a JKQTPlotter widget (as a new window) and adds a color-coded image plot of a mathematical function (here the Airy disk). The image is stored as a simple C-array in row-major ordering and then given to a JKQTPMathImage to visualize it. The data is stored as a pointer directly in the JKQTPMathImage object. There is also a variant JKQTPColumnMathImage of JKQTPMathImage, which references a column in the internal JKQTdatastore and uses the data there for plotting. In both cases data has to be organized as a row-major matrix of values. JKQTPMathImage supports different dataytpes ([u]nit8/16/32/64,float,double see `JKQTPMathImageBase::DataType`) that can be configured e.g. by `set_data()`.

 The second variant for setting the color of each datapoint is by mapping the values in the column to a color palette (`JKQTPMathImageRYGB` in this example). For this you simply need to define the color coumn and the palette to use. By default, the color palette spans the full range of values in `colorColumn`:
 ```.cpp
    JKQTPXYParametrizedScatterGraph* graph2=new JKQTPXYParametrizedScatterGraph(&plot);

-    graph2->set_symbol(JKQTPFilledRect);
-    graph2->set_drawLine(true);
-    graph2->set_title("2: color");
-    graph2->get_colorBarRightAxis()->setAxisLabel("color scale for graph2");

+    graph2->getColorBarRightAxis()->setAxisLabel("color scale for graph2");
    plot.addGraph(graph2);
 ```
-Note: If you want to set the range manually, use `ste_imageMin()` and `set_imageMax()` after setting `set_autoImageRange(false)`.
