Plot View¶
Last Updated: August 10, 2015
Tethys Platform provides two interactive plotting engines: D3 and Highcharts. The Plot view options objects have been designed to be engine independent, meaning that you can configure a D3 plot using the same syntax as a Highcharts plot. This allows you to switch which plotting engine to use via configuration. This article describes each of the plot views that are available.
Warning
Highcharts is free-of-charge for certain applications (see: Highcharts JS Licensing). If you need a guaranteed fee-free solution, D3 is recommended.
Note
D3 plotting implemented for Line Plot, Pie Plot, Bar Plot, Scatter Plot, and Timeseries Plot.

JavaScript API¶
For advanced features, the JavaScript API can be used to interact with the HighCharts object that is generated by the Plot View JavaScript library.
TETHYS_PLOT_VIEW.initHighChartsPlot(jquery_element)¶
This method initializes a chart generated from an AJAX request. An example is demonstrated in the Dam Break javascript tutorial.
Note
In order to use this, you will either need to use a PlotView
gizmo on
the main page or register the dependencies in the main html template page
using the import_gizmo_dependency
tag with the plot_view
name
in the import_gizmos
block.
For example:
{% block import_gizmos %}
{% import_gizmo_dependency plot_view %}
{% endblock %}
Four elements are required:
1) A controller for the AJAX call with a plot view gizmo.
@login_required()
def hydrograph_ajax(request):
"""
Controller for the hydrograph ajax request.
"""
# add a plot view gizmo
flood_plot = TimeSeries(
...
)
context = {'flood_plot': flood_plot}
return render(request, 'dam_break/hydrograph_ajax.html', context)
2) A template for with the tethys gizmo (e.g. hydrograph_ajax.html)
{% load tethys_gizmos %}
{% gizmo flood_plot %}
3) A url map to the controller in app.py
...
UrlMap(name='hydrograph_ajax',
url='dam-break/map/hydrograph',
controller='dam_break.controllers.hydrograph_ajax'),
...
4) The AJAX call in the javascript
$(function() { //wait for page to load
$.ajax({
url: 'hydrograph',
method: 'GET',

Highcharts JavaScript API¶
The Highcharts plots can be modified via JavaScript by using jQuery to select the Highcharts div and calling the highcharts()
method on it. This will return the JavaScript object that represents the plot, which can be modified using the Highcharts API.
var plot = $('#my-plot').highcharts();
