Error bars are implemented in the mixin-classes `JKQTPxyGraphErrors`, `JKQTPxGraphErrors` and `JKQTPyGraphErrors` that are all derived from `JKQTPgraphErrors`. With these it is simple to add error indicators to several different plot styles. Usually you can recognize these by looking at the class name, e.g. `JKQTPxyLineGraph` is a simple line+symbol graph, and `JKQTPxyLineErrorGraph` is the same with error indictaors (see above). There are also several other plots with error indicators:

This project (see `./examples/simpletest_imageplot/`) 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 copied into a single column of the internal datasdtore (JKQTPMathImage could be directly used without the internal datastore). This very simple interface can also be used to interface with many common image processing libraries, like CImg or OpenCV.

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()`.

This project (see `./examples/simpletest_imageplot_opencv/`) 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 generated as an OpenCV cv::Mat image and then copied into a single column of the internal datasdtore (JKQTPMathImage could be directly used without the internal datastore).

The simplest case is to modify the symbol type. Simply set the property `symbolColumn` with `graph1->set_symbolColumn(columnP)` to a data column. The values in the data column will be cast to an integer and then will be translated to `JKQTPgraphSymbols`. If the numbers are larger than the available symbol types in `JKQTPgraphSymbols`, the graph will cycle through the available symbols (via a modulo-operation with the max. symbol count!).

In this example, we load an image, convert it to greyscale and store it, together with x/y-coordinate-vectors in the datastore. Then a `JKQTPxyParametrizedScatterGraph` is used to draw the image as a pointilistic artwork, where each pixel is represented by a disk. The color of the disk is chosen from a color-palette, based on the grey-value. The size of each disk is chosen from the inverse grey value.

As you can see a graph of the type `JKQTPxParsedFunctionLineGraph` is used, which plots a function that depends on the variable `x`. The given function is parsed and evaluated (see [`lib/jkqtplottertools/jkqtpmathparser.h`](https://github.com/jkriege2/JKQtPlotter/blob/master/lib/jkqtplottertools/jkqtpmathparser.h) for details on the features of the math parser). An intelligent drawing algorithm chooses the number of control points for drawing a smooth graph, with sufficient amount of details, by evaluating locally the slope of the function.

These parameters can be double numbers and may be set with either as an internal parameter vector, or may be read from a parameter column (as shown in the [linked example](../simpletest_functionplot)).
