BIMxHTML v0.0.8 – More Custom Nodes to Generate Google Charts

It looks like there has been some interest in the BIMxHTML Dynamo package and its encouraged me to develop some custom nodes to simplify the display of Google Charts using pure Dynamo.

The Custom Nodes

Download the sample files below to get a good example of how to use these nodes. Essentially, they output an entire web page and as of today the intent is to use them in the iframes of a dashboard.

Data Set – Quantities of Family Types.dyf

Use this node to build a dictionary of family types of any given category. The output is actually a list of sublists which contain the [key, value] pairs as [family type, quantity]. For example:  [Diffuser24x24, 17].

This node is helpful to use for the input of any of the Google Chart nodes.

Create a data set for use as input to the BIMxHTML nodes.

Generate Web Page – Google Pie Chart.dyf

Creates the complete web page to display a responsive pie chart based on the Google Charts API. The intent for the HTML file is to reference it in an iframe for a dashboard (more on that to come).

Refer to the Google Charts documentation for options input.

Create the HTML for a Google Pie Chart.

Generate Web Page – Google Bar Chart.dyf

This node takes the same exact input as the Pie Chart node and outputs a bar graph.

Refer to the Google Charts documentation for options input.

Create the HTML for a Google Bar Chart.

Sample Files

Refer to the sample Dynamo graphs below to get a better idea of how to use these nodes. Dashboard-Mech.html is currently the best example because it displays a pie chart, a bar chart, and a table – all generated directly from Dynamo.

BIMxHTML – A Dynamo Package to Generate Web Pages

All of the excitement revolving around generating dashboards using Power BI made me wonder: Can we leverage Dynamo to create web pages that display data directly from a Revit model? The goal would be to create a powerful, free alternative to generating web-based content using simple HTML code.

Needless to say, the gears have been turning and I have been experimenting. With that said, I have published my first Dynamo package, BIMxHTML, which will eventually have several nodes to display content on a web page using very basic HTML. I have been playing with Twitter Bootstrap and Google Charts so far.

Update: New nodes have been published to v0.0.8 which streamline the creation of Google Charts. Read up on the nodes here:

For now a single node is included in the BIMxHTML package: Generate Web Page.

Using Dynamo node to create a static HTML web page.

The inputs for Generate Web Page contain several default values for configuring the <head> of the web page. I have also included inputs to allow users to link to external CSS stylesheets and JavaScript files or embedded code for custom <style> or <script> tags. All without managing the template’s HTML directly.

I have a sample model and graph for you to see the node in action available for download below.

Sample Files Explained

There are a few sample graphs included in the download below. Please keep in mind that these are extremely early examples of the possibilities of using Dynamo to extract Revit data and output HTML for display in any modern browser. Currently, I have been experimenting with a combination of Twitter Bootstrap and Google Charts, but if you have any suggestions on other frameworks or analytics tools, please make a suggestion in the comments below.

Table Sample.dyn (TableTest.html)

Creates a list with parameter values as sublists.

  1. Using Python, the HTML code for a table is generated using each list item as a table row and each sublist item as a column value. Note: a custom node will be added to this package to handle this in the near future.
  2. Finally, the Generate Web Page node from the BIMxHTML package creates the entire web page’s code and then writes the code to an external HTML file.

Google Charts – Pie Chart.dyn (Air Terminals.html / Ducts.html)

Creates an HTML page containing a Google Charts pie chart displaying the quantity of family types per category.
