# The Plot Menu

This menu is active only when a table is selected. These commands allow to plot the data selected in the active table.

Line

  Plots the selected data columns in the active table window using the "Line" style. This command can also be activated by clinking on the icon of the Table toolbar. Once the plot is created, the drawing of the data series can be customized with the Custom curves dialog.

Scatter

  Plots the selected data columns in the active table window using the "Scatter" style. This command can also be activated by clinking on the icon of the Table toolbar. Once the plot is created, the drawing of the data series can be customized with the Custom curves dialog.

Line+Symbol

  Plots the selected data columns in the active table window using the "Line + Symbol" style.This command can also be activated by clinking on the icon of the Table toolbar. Once the plot is created, the drawing of the data series can be customized with the Custom curves dialog.

Special Line+Symbol ->

  Vertical Drop Lines

    Plots the selected data columns in the active table window using the "Vertical drop lines" style. Once the plot is created, the drawing of the data series can be customized with the Custom curves dialog.

  Spline

    Plots the selected data columns in the active table window using the "Spline" style. Once the plot is created, the drawing of the data series can be customized with the Custom curves dialog.

  Vertical Steps

    Plots the selected data columns in the active table window using the "Vertical Steps" style. Once the plot is created, the drawing of the data series can be customized with the Custom curves dialog.

  Horizontal Steps

    Plots the selected data columns in the active table window using the "Horizontal Steps" style. Once the plot is created, the drawing of the data series can be customized with the Custom curves dialog.

  Double-Y

    Creates a double Y axis graph. Requires a selection of at least two Y columns (or a range from at least two columns).

Columns

  Plots the selected data columns in the active table window using the "Columns" style, that is vertical bars.

Rows

  Plots the selected data columns in the active table window using the "Rows" style.

Area

  Plots the selected data columns in the active table window using the "Area" style.

Pie

  Creates a 2D Pie plot of the selected column in the active table window (only one column allowed).

Vectors XYXY

  Creates a vectors plot of the selected column in the active table window. You must select four columns for this particular type of plot. The two first columns give the coordinates for the starting points of the vectors, the two last columns giving the information regarding the end points.

Vectors XYAM

  Creates a vectors plot of the selected column in the active table window. You must select four columns for this particular type of plot. The two first columns give the coordinates for the starting points of the vectors, the two last columns giving the angle (in radians) and the magnitude of the vectors.

Statistical Graphs ->

  Statistical plot will not give a direct drawing of the data selected in the table, but they will give a representation of the frequency distribution of the Y-values.

  Statistical Graphs -> Box Plot

    Creates a box plot of the selected data columns in the active table window. This type of plot is used to give a graphical representation of the some classical parameters of the frequency distribution such as the mean of data, the min and max values, the position of the 95 and 5 percentiles, etc. The choice of the statistical parameters and the graphical parameters can be modified with the Custom curves dialog.

  Statistical Graphs -> Histogram

    Creates a frequency histograms of the selected data columns in the active table window. The default binning uses 10 steps between the max and the min of Y-values. This can be modified with the Custom curves dialog.

    With this command, a frequency distribution is computed from your data. If you want to draw an histogram directly from values, use the Bars.

  Statistical Graphs -> Stacked Histogram

    Creates vertically stacked layers displaying the histograms of the selected data columns in the active table window (one histogram per layer) See the Panel -> Vertical 2 Layers command for more details.

Panel ->

  These commands can be used to obtain quickly some classical arrangements of multiple plot.

  Panel -> Vertical 2 Layers

    Creates 2 vertically stacked layers displaying the selected data columns in the active table window (one curve per layer).

  Panel -> Horizontal 2 Layers

    Creates 2 horizontally stacked layers displaying the selected data columns in the active table window (one curve per layer).

  Panel -> 4 Layers

    Creates 4 layers on a 2x2 grid, displaying the selected data columns in the active table window (one curve per layer).

  Panel -> Stacked Layers

    Creates vertically stacked layers displaying the selected data columns in the active table window (one curve per layer).

Data -> Plot 3D ->

  Plot 3D -> Ribbons

    Makes a 3D plot of the selected data column in the active table window (only one column allowed) using the "Ribbon" style.

  Bars

    Makes a 3D plot of the selected data column in the active table window (only one column allowed) using the "3D Bars" style.

  Scatter

    Makes a 3D plot of the selected data column in the active table window (only one column allowed) using the "3D Dots" style. The 3D point symbol style can be changed via the 3D Plots Settings dialog.

    With scatter plots, you can choose the kind of graphic item which is used to plot the data points. The example above is done with cross hairs, but you can also select points or cones. This can be done either with the corresponding icons of the 3D plot toolbar (respectively and for cross-hairs, dots and cones) or with the custom-curves dialog.

  Plot 3D -> Trajectory

    Makes a 3D plot of the selected data column in the active table window (only one column allowed) using the "3D Line" style. The line width and color may be changed via the 3D Plots Settings dialog.
