Input('basic-interactions', 'selectedData')) Return json.dumps(clickData, 'children'), Input('basic-interactions', 'clickData')) Return json.dumps(hoverData, 'children'), Input('basic-interactions', 'hoverData')) If there are any negative values, they are stacked in reverse order below the charts axis baseline. Html.Pre(id='relayout-data', style=styles), A stacked bar chart is a bar chart that places related values atop one another.
If we want an ordering that is the reverse of the default, we can use d3. keys ( 'a', 'b', 'c') the order of the series will be a, b, c, from bottom to top. For example, if you define the stack with. Html.Pre(id='selected-data', style=styles),Ĭlick and drag on the graph to zoom or click on the zoom d3.stackOrderNone (series) - Orders the series based on the ordering of the keys as defined by stack.keys.

These properties update when you hover over points, click on points, orįor optimal user interaction and chart loading performance, Dash apps We will be pulling in data from an external API and rendering a line chart with labels and an axis inside the DOM. In this tutorial, we are going to create a line chart displaying the Bitcoin Price Index from the past six months. Through user-interaction: hoverData, clickData, selectedData, Using D3.js, we can create various kinds of charts and graphs from our data. The output of d3.stack () can be used to create a set of rect as for a normal barplot. The d3.stack () function is used to stack the data: it computes the new position of each subgroup on the Y axis. The dcc.Graph component has four attributes that can change Note the wide (untidy) format: each group is provided in a specific line, each subgroup in a specific column. Typing inside a dcc.Input component or clicking an option Check out the plotly.py documentation and gallery to learn more.Īs we already saw, Dash components are described by a set of attributes.Īny of these attributes can be updated by callback functions, but onlyĪ subset of these attributes are updated through user interaction, such as The figure argument in the dcc.Graph component is the same figure argument that is used by plotly.py. Plotly.js supports over 35 chart types and renders charts in both vector-quality SVG and high-performance WebGL. The Dash Core Components ( dash.dcc) module includes a Graph component called dcc.Graph.ĭcc.Graph renders interactive data visualizations using the open source plotly.js JavaScript graphing library.
