this function is used to plot error inidcators before plotting the graphs.
Reimplemented from JKQTPGraph.

get the maximum and minimum x-value of the graph
The result is given in the two parameters which are call-by-reference parameters!
| [out] | minx | minimal x-value used in the graph |
| [out] | maxx | maximal x-value used in the graph |
| [out] | smallestGreaterZero | the smalles x-value in the graph, which is larger than 0 (this is used in auto-sizing for logarithmic axes) |
true on success, i.e. if there were datapoints in the plot, or false on failure (e.g. when the graph is empty) Reimplemented from JKQTPXYGraph.

The result is given in the two parameters which are call-by-reference parameters!
| [out] | miny | minimal y-value used in the graph |
| [out] | maxy | maximal y-value used in the graph |
| [out] | smallestGreaterZero | the smalles y-value in the graph, which is larger than 0 (this is used in auto-sizing for logarithmic axes) |

overridevirtual |
returns true if the given column is used by the graph
This virtual function indicates whether a given column is used by this graph. Override this function in your derived graphs to indicate to JKQTPlotter / JKQTBasePlotter , which columns from the internal JKQTPDatastore are actually used. This information can be used e.g. for graph-specific data-export.
