====== Time chart ======

A time chart plots simulation outputs against time. Outputs that are not time-dependent, such as parameters, will be plotted as straight lines.

===== Creating a time chart =====

From the [[Results_window|results window]] (Recommended)

  * Select at least one time dependent output. This will create a [[Quick_view|quick view]] which, by default, is a [[Time_chart|time chart]] for time dependent outputs. //Or//,
  * Right-click the output or outputs that you wish to plot and select **Time Chart** from the popup-menu

From the [[Charts_window|charts window]]

  * Click the {{:ChartView24.png}} button, //or//
  * Right-click the charts window and select **Create | Time Chart** from the popup-menu

===== Editing a time chart =====

Some properties can be changed directly by using the controls below the chart. For a time chart there are controls for:

  * **Legend** - Toggle legend on/off
  * **Lines** - Toggle lines drawn between points on/off
  * **Shapes** - Toggle shapes drawn at points on/off
  * **Log-x** - Toggle log scale for x-axis on/off
  * **Log-y** - Toggle log scale for y-axis on/off

To change other properties either right-click the chart in the [[Charts_window|charts window]] and select **Edit**, or double-click the chart, or click the {{:Edit24.png|Edit}} button in the title bar. __The chart editor has two tabs:__

==== Properties ====

This screen let you edit properties such as name and axes, that are common to most charts. Please see [[Editing_chart_properties|editing chart properties]] for more information.

==== Data ====

  * **Outputs** - Select simulation outputs from the left hand list by using the arrow buttons.
  * **Time series** - You can use the simulation output time, or specify a custom time series. When you create a custom time series, the simulation output data will be interpolated for these time points. A custom time series is created in the same manner as in [[Simulation_settings|simulation settings]].

  * **Statistics** - This panel is only available for probabilistic data and makes it possible to add several graphs with different statistical properties.
    * Mean - Check this box to add a graph with mean values for the outputs.
    * Median - Check this box to add a graph with median values for the outputs.
    * Lower percentile - Check this box and enter a value 0>x>100 to add a graph with the given percentile for the outputs.
    * Upper percentile - Check this box and enter a value 0>x>100 to add a graph with the given percentile for the outputs.
    * Iteration - Check this box to plot a given iteration or all iterations. To plot a specific iteration, enter a number in the field, otherwise select the **All** box.
