            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:

            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:

            I don't think there is a file that Altair reads at startup. If you want to avoid copy pasting the same theme code into each notebook, you can create a Python package with your theme. There are several examples of how to set this up on GitHub e.g. this la times theme.

            Recreating the pyLDAvis chart in Altair - filtered data with empty selection
            Asked 2021-Jun-11 at 04:10

            I am trying to recreating the classic pyLDAvis visualization for topic modelling in Altair.

            I've hit a snag when it comes to filtering. In the pyLDAvis chart, an empty selection in the scatter chart shows the so-called "Default" topic in the right chart which just shows the total frequencies for each word in the corpus.

            On the other hand, if you make a selection in the scatter chart, the bar chart is filtered so that it shows the totals for the selection, overlayed against the overall totals as shown below:

            I can get close to this, but as you can see below, there are (at least) two differences:

            • my filtered bar chart shows all the segments when there is no selection and,
            • only one topic is shown when I make a selection (i.e., there is no overlay)

            Does anyone know how I could get closer based on the issues above? That is, I'd like to show only the totals when there is no selection and to overlay the selection with the totals when a point is clicked.

            Reproducible Altair code below:

            You could overlay a separate bar plot on top of the first one and only use transform filter on this overlaid plot. To not show any segments on the start you can set the empty behavior of the selection.

            Why does the leftmost bar in an Altair Bar Chart not respect the selection brush location?
            Asked 2021-Jun-06 at 15:14

            I created a simple bar chart based off of synthetic data, generated within the code below (generate_dataframe). The image has a top chart with the data and a lower chart that allows me to drag a selection along the horizontal axis. There appears to be an error: the leftmost bar is not affected by the motion of my selection in the lower plot. I use streamlit to display the plot. Here is an image of what is happening. I list the code below the image. Thanks for any advice.

            Binding an interval selection to a scale's domain is currently not supported for ordinal and nominal domains. A workaround is to use .transform_filter() instead, so change your code to this and you will no longer see the stacked bar to the left:

            Altair interval selection in concatenated charts with 'density', 'aggregate' and 'calculate' transforms
            Asked 2021-Jun-02 at 21:01

            I have two concatenated charts built on the same DF. The left one shows a density transform of one data column, the right one shows a scatter plot of aggregates of other data columns.

            I would like to do an interval selection on the left side and filter transform the right side accordingly. No matter what I select, however, the right side loses all data points.

            I had a similar problem and solved it as follows

            1. create a list to store the pages or elements of the report, such as
            • report_pages=[]
            • report_pages.append(dp.Page)
            • report_pages.append(dp.Table)
            • report_pages.append(dp.Plot)
            1. At the end just generate the report with a pointer to the list
            • dp.Report(*pages)

            In your case, I think you can do the following

            1. create a list
            • rows=[]
            1. add the rows to the list
            • rows.append(row_1)
            • rows.append(row_2)
            1. and then create the report with
            • r= dp.Report(*rows)

            I found this solution on datapane's github https://github.com/datapane/gallery and then in the notebook https://mybinder.org/v2/gh/khuyentran1401/Machine_Learning/ce7fae1c5d9fab8eefcd624674c10afaa1704bbd?filepath=machine_learning%2FSVM_Decision_Boundary%2FDecision_Boundary_SVM.ipynb in the last line of code.

            I hope to have helped.
