Draws/writes data/line information in legend in plot window.
legend, data"["[,type=type ] [,panel=panel ] [,num=num ] [,str=str ] [,plotwidth=plotwidth ] [,xlist=xlist ] [,ylist=ylist ] [,margin=margin] "]"
type - Data type to show. This corresponds essentially to the plot type(s) used for the plot.
> legend,data[type=data]+data[type=model] -> Display data/model information only. panel- The panel to show only. num - Select only the legend entry with given number (integer). This input allows to build manually a data list with given points. str - Apply the string "str" to all selected data entries. Should be used in conjunction with num to select a single data entry (if not only one is given). plotwidth - Define width of data point item to plot. This is given in normal units (ranging from 0..1 for full screen). Default is 0.02. xlist - Vector of data point item x-values. The list should contain x-values for points ranging from 0..1 (the plotwidth). The number of entries must be the same as in ylist. Default are 3 points:[0,0.5,1] ylist - Vector of data point item y-values. The list should contain y-values for points ranging from -0.5 .. 0.5. The number of entries must be the same as in xlist. Default are 3 points:[0,0,0] (equal y value). margin - Space between plot item and left border/right text in units of Plotwidth. Default is 0.5.
The options "plotwidth", "xlist", ylist" and "margin" may be set with the "set" command. The command prefix is "legend_data".
For each plot type used a legend entry will be drawn in respect of line color, style and point symbols.
Changes plot window.
> fit > plot, data+model > legend, data -> creates legend with two entries - the data and the model.
