Reveal 1.6.0 Features Are Here!!

Welcome to Reveal 1.6.0! This release brings a host of enhancements, bug fixes, and exciting new features that will refine the way you interact with your data.

In this blog post, we’ll dive into the key highlights, with a particular focus on two standout features: custom visualizations and interactive chart filtering.

DIY Custom Visualizations with Reveal  

With this innovative addition to our platform, you can now control the chart types available within your dashboards. Tailor the experience for your users by removing any of our default chart types that may not be relevant to your specific needs. Create customized groups to organize the chart types efficiently, ensuring an intuitive and user-friendly interface.  

What’s more, you can instantly incorporate your custom visualizations, replete with names and icons, with just four lines of code, bringing up a universe of possibilities for showing your data in new and exciting ways. 

1. Update Chart Type: ​To update an existing chart type, find the chart type in the revealView.chartTypes property. Modify the various properties of the chart type to either rename, change the icon, or regroup the chart type item. 

var barConfig = revealView.chartTypes.find(x => x.chartType == 'BarChart'); 
barConfig.title = 'My Cool Bar'; 
barConfig.icon = 'https://help.revealbi.io/img/logo.png'; 
barConfig.groups = ["Enterprise Visualizations", "HR", "Some Other Category"]; 

2. Remove Chart Type: Remove a chart type by finding the index of the chart type item you want removed, and remove it from the chartTypes array. 

var gridConfig = revealView.chartTypes.find(x => x.chartType == 'Grid'); 
revealView.chartTypes.splice(revealView.chartTypes.indexOf(gridConfig), 1);

3. Add Custom Chart Type: Besides updating and removing existing chart type items, you can also add your Custom Visualizations as a new chart type in the Chart Types drop down. 

revealView.chartTypes.push({ 
    title: "Custom Viz", 
    url: "https://host/customViz.html", //provide the url to your custom visualization 
    icon: "https://help.revealbi.io/img/logo.png", 
    groups: ["Custom Visualizations"] 
});

Interactive Chart Filtering  

Reveal’s latest 1.6.0 release introduces Interactive Chart Filtering, a dynamic data manipulation feature that puts the power of real-time data exploration at your fingertips. This seamless and intuitive experience allows you to filter your entire dashboard on the fly, revolutionizing the way you interact with your data. Here’s how it works: 

1. Enable chart actions available while hovering the mouse. To turn on, use:

revealView.interactiveFilteringEnabled = true; 
$.ig.RevealSdkSettings.enableActionsOnHoverTooltip = true 

2. Hover and click over any data point within your chart to dynamically filter your dashboard to that specific data point. 

3. You can continue to add additional filters and remove filters as your dashboard reflects your selections in real-time.  

With this dynamic feature, you’ll effortlessly gain the insights you need to answer your data-driven questions, making data exploration more engaging and intuitive than ever before. Say goodbye to manual filter input and welcome a more dynamic and responsive data discovery with Reveal.
