to_dict() → dict

Generate a dict representation of the object compatible with the Highcharts JavaScript library.

Note

The dict representation has a property structure and naming convention that is intentionally consistent with the Highcharts JavaScript library. This is not Pythonic, but it makes managing the interplay between the two languages much, much simpler.

untrimmed (dict) – The dict whose values may still be None or Python objects.
to_json (bool) – If True, will remove all keys from untrimmed that are not serializable to JSON. Defaults to False.
context (str or None) – If provided, will inform the method of the context in which it is being run which may inform special handling cases (e.g. where empty strings may be important / allowable). Defaults to None.
for_export (bool) – If True, indicates that the method is being run to produce a JSON for consumption by the export server. Defaults to False.

Returns:

Trimmed dict

Return type:

dict

to_json (bool) – If True, will remove all members from untrimmed that are not serializable to JSON. Defaults to False.
context (str or None) – If provided, will inform the method of the context in which it is being run which may inform special handling cases (e.g. where empty strings may be important / allowable). Defaults to None.
for_export (bool) – If True, indicates that the method is being run to produce a JSON for consumption by the export server. Defaults to False.

Return type:

iterable

property align_thresholds: bool | None

When using multiple axes, align the thresholds. When True, other ticks will also be aligned. Defaults to False.

Note

For line series and some other series types, the threshold option is set to null by default. This will in turn cause their y-axis to not have a threshold. In order to avoid that, set the series threshold to 0 or another number.

Note

If AxisOptions.start_on_tick() or AxisOptions.end_on_tick() are set to False, or if the axis is logarithmic, the threshold will not be aligned.

Returns:: Flag indicating whether thresholds should be aligned.
Return type:: bool or None

property align_ticks: bool | None

If True and using multiple axes, the ticks of two or more opposite axes will automatically be aligned by adding ticks to the axis or axes with the least ticks, as if tick_amount were specified. This can be prevented by setting align_ticks to False.

Defaults to True.

Hint

If the grid lines look messy, it’s a good idea to hide them for the secondary axis by setting grid_line_width to 0.

Warning

If start_on_tick or end_on_tick in the axis options are set to False, then tick alignment will be disabled for the axis.

Warning

Aways disabled for logarithmic axes.

Returns:: Flag indicating whether ot align ticks along the axes.
Return type:: bool or None

property allow_mutating_data: bool | None

If True, the original data source will be allowed to be mutated. However, if False then Highcharts will create a copy of the original data to prevent inadvertent mutation. Defaults to True.

Note

By default, (for memory and performance reasons) the chart does not copy the data but keeps it as a reference.

In some cases, this might result in mutating the original data source. In order to prevent that, set this property to False. Please note that changing this may decrease performance, especially with bigger sets of data.

Returns:: Flag indicating whether to allow mutation by referencing th eoriginal data (True), or prevent it by copying the original data (False).
Return type:: bool or None

property animation: bool | AnimationOptions | None

Configures the overall animation for all chart updating.

The animation can be configured as either a boolean or a AnimationOptions object. If True, it will apply the 'swing' jQuery easing and a duration of 500 ms by default. If used as a AnimationOptions instance, you have more fine-grianed configuration control.

Animation can be disabled throughout the chart by setting it to False here. It can be overridden for each individual API method as a function parameter. The only animation not affected by this option is the initial series animation, see PlotOptions.series.animation().

When zooming on a series with less than 100 points, the chart redraw will be done with animation, but in case of more data points, it is necessary to set this option to ensure animation on zoom.

Returns:: Settings for the animation of image patterns.
Return type:: AnimationOptions or None

property axis_layout_runs: int | None

The number of axis layout runs to execute when rendering the chart. Defaults to 2.

Note

When a chart with an x and a y-axis is rendered, we first pre-render the labels of both in order to measure them. Then, if either of the axis labels take up so much space that it significantly affects the length of the other axis, we repeat the process.

By default we stop at two axis layout runs, but it may be that the second run also alters the space required by either axis, for example if it causes the labels to rotate. In this situation, a subsequent redraw of the chart may cause the tick and label placement to change for apparently no reason.

Use the .axis_layout_runs property to set the maximum allowed number of repetitions.

Warning

Keep in mind that the default value of 2 is set because every run costs performance time. Changing this value option to higher than the default might decrease performance significantly, especially with bigger sets of data.

Returns:: The maximum allowed number of axis layout runs.
Return type:: int

With ten colors, series (or points) are given class names like highcharts-color-0, highcharts-color-0 […] highcharts-color-9. The equivalent in non-styled mode is to set colors using the colors setting.

Returns:: The number of colors to cycle through in styled mode.
Return type:: int or None

Return type:: bool or None

property events: ChartEvents | None

Definition of JavaScript event listeners to apply to the chart.

Return type:: ChartEvents or None

An explicit height for the chart. Defaults to None.

If a number, the height is given in pixels. If given a percentage string (for example '56%'), the height is given as the percentage of the actual chart width. This allows for preserving the aspect ratio across responsive sizes.

By default (when None python:None>) the height is calculated from the offset height of the containing element, or 400 pixels if the containing element’s height is 0.

Return type:: EnforcedNullType or numeric or str or None

property ignore_hidden_series: bool | None

If True, the axes will scale to the remaining visible series once one series is hidden. If False, hiding and showing a series will not affect the axes or the other series.

Defaults to True.

Note

For stacks, once one series within the stack is hidden, the rest of the stack will close in around it even if the axis is not affected.

Returns:: Flag indicating whether to ignore hidden series.
Return type:: bool or None

property inverted: bool | None

If True, inverts the axes so that the x-axis is vertical and y-axis is horizontal. Defaults to False.

Hint

When True, the x-axis is reversed by default.

Warning

If a bar series is present in the chart, it will be inverted automatically.

Hint

Inverting the chart doesn’t have an effect if there are no cartesian series in the chart, or if the chart is a polar chart type.

Returns:: Flag indicating whether to invert the axes.
Return type:: bool or None

This scrollbar provides smooth scrolling for the contents of the plot area, whereas the title, legend and unaffected axes are fixed.

Hint
