QUESTION

Sorting a chart axis based on the dynamically updated axis order in another chart

Asked 2021-Jun-12 at 13:34

In this VegaLite spec the y-axis order of the bottom-most barplot is updated as the data of that plot is filtered based on the selection in the scatter plot. How can I achieve the same resorting behavior for both the blue and orange bars in the top-most bar plot where I have layered the same barplot together with another chart?

I have tried toggling the axis between shared and independent and switching the order of the layer, but that didn't do it. Conceptually I can imagine using a calculate transform to define a new field that is based on the selection and used as the sort order key, but I can't figure out how to write this vega expression string.

Here is that Altair code if anyone prefers to solve it that way:

ANSWER

Answered 2021-Jun-12 at 13:34

The issue with your spec was that in layers you performed filter transform which created a separate data for each layers. Sorting was working at each level of layer but since both the layers data were separate so each layer was getting sorted inpendently.

So instead of having a filter transform, I tried to manual filter using calculate transform and created a filtered_freq_x field which is later used on 2nd layer and performed sorting using this on window. So with this my data becomes same for both layers, just few fields were added and used.

Let me know if this works for you not. Below is the spec config and editor:

Conditional render label Color base on another field value

Asked 2021-Jun-03 at 12:13

I'm trying to render the label color base on another field value using test predicate or field predicate but I can not get it right. All I want is that the label color on axis y (section) can change from black to red when its resilience value equal to 0.
I've made my code on online editor and I really appreciate if you can give me some help.

in the case above, the fifth one <4. Hygiene & Cleaning> should be red instead of black.

You will need vega-lite, vega-cli and vega-embed to create a vega-lite chart. You can check the devDependencies for the selected version of vega-lite. For example, in package.json of vega-lite v5.1.0, these are the required dependencies:

To display the concatenated value of 2 fields "29 (14%)" over text you can use transform calculate and generate a concatenated string based on your field. Then, use that field in your text mark as done below or refer editor:

vega-lite: is it possible to render only the legend without the reference chart?

ANSWER

Answered 2021-May-14 at 16:59

I don't know of a built-in way to display only the legend, but you can hack it by removing all positional encodings, setting the mark opacity to zero, and setting the view width/height to 0. For example, here is a way to generate just the legend from this Vega-Lite example:

I'm playing with vega-lite v5 and the new parameters and wanted to change the order of marks using an input element:

Is that possible?

I looked into the examples in the documentation but neither on x's order property or with an order encoding I was able to use the param.

ANSWER

Answered 2021-May-13 at 08:08

Yes you can do this by sorting the data with a window transform. Although undocumented as of VL 5.1.0, window properties can be parameterised with signal values (and should take expr values with the next update). Here's a working example that separates your input element into the field to sort by and the direction to sort.
