class eelbrain.plot.LineStack(y, x=None, sub=None, ds=None, offset='y.max() - y.min()', ylim=None, xlim=None, xlabel=True, xticklabels=True, ylabel=True, order=None, colors=None, ylabels=True, xdim=None, legend=None, labels=None, clip=None, **kwargs)

Stack multiple lines vertically

  • y (NDVar) – Values to plot.

  • x (cateorial) – Variable to aggregate cases into lines (default is to plot each line).

  • sub (None | index array) – Only use a subset of the data provided.

  • ds (Dataset) – If a Dataset is specified, all data-objects can be specified as names of Dataset variables.

  • offset (float | str) – The distance between the baseline (y = 0) for the different lines. Can be a string expressed as a function of y. For example, '0.66 * max(y)' will offset each line by 0.66 times the maximum value in y (after aggregating if x is specified). The default is '2/3 * max(y.max(), -y.min())'.

  • xlim (scalar | (scalar, scalar)) – Initial x-axis view limits as (left, right) tuple or as length scalar (default is the full x-axis in the data).

  • xlabel (bool | str) – X-axis label. By default the label is inferred from the data.

  • xticklabels (bool) – Print x-axis tick-labels (set to False to suppress them).

  • ylabel (bool | str) – Y-axis label. By default the label is inferred from the data.

  • colors (dict | sequence of colors) – Colors for the lines (default is all lines in black).

  • ylabels (bool | dict | sequence of str) – Labels for the different lines, placed along the y-axis.

  • legend (str | int | 'fig' | None) – Matplotlib figure legend location argument or ‘fig’ to plot the legend in a separate figure.

  • labels (dict) – Alternative labels for legend as {cell: label} dictionary (preserves order).

  • clip (bool) – Clip lines outside of axes (the default depends on whether frame is closed or open).

  • ... – Also accepts General layout parameters.


  • : scroll left

  • : scroll right

  • home: scroll to beginning

  • end: scroll to end

  • f: x-axis zoom in (reduce x axis range)

  • d: x-axis zoom out (increase x axis range)
