We ❤ Power BI so much we created a custom visual

About a year ago (March 2020) We needed a line chart that can do the following:

  • Allow the viewer of the report to change the Y axis scale on the fly
  • Allow the X axis to be placed near the top of the chart
  • Have the ability to invert the Y axis*

When we started, we didn’t want to reinvent the wheel, so we searched first but couldn’t find a chart on the App Source marketplace that could do all of these thing I listed above*. So we started creating our first custom Power BI Chart Visual: CHARTURO

Power BI Switching between Logarithmic and Linear Scales

Welcome to the second post in our miniseries: “Are You Developing Power BI Reports the Right Way?” In the two-part series we are designing a sample Power BI report visualizing the weather on Mars and using some real world techniques.

The highlights of our first post were:

    • Getting data from Mars
    • Using a JSON file as a data source
    • Performing operations in the “Get Data” phase using M
    • Implementing a Dynamic Slicer
    • Using Chiclet Slicer and Dummyimage to create a Legend Slicer
    • Making design decisions

Note: Due to the popularity of this article, we have developed a custom Power BI line chart visual that is published to the Power BI AppSource Marketplace and has built-in support for allowing the end users to switch the axis scales, read about it in @Talal’s post. and viewing them in Power BI Desktop.

This post will focus on:

    • Switching an Axis Between Logarithmic and Linear Scales via a Slicer
    • Adding a Date Slicer
    • Using a Dark Theme
