Describe the bug

The web app doesn't display the beautiful histogram plots like it used to and renders rather ugly-looking teal rectangles instead.
Example

OS: macOS Sequoia 15.1
Browser: Safari 18.1 and firefox 131.0.3 (tested both)

hello @ddonatien , thank you for writing in and happy to help. Could you please try to Edit Panel this specific chart. From Data tab, look for Point Aggregation Method, and see if it is defaulted to Full Fidelity. Then try to change to Random Sampling and try to adjust the Smoothing option. Image
Let us know the result~

Hello, thank you for your help.
I have tried different smoothing options with random sampling but to no avail.
Here are a few examples:
Random sampling w/ TW EMA 0.49:

Random sampling w/ Gaussian 45:

Full fidelity, min/max Always:

Full fidelity, min/max On Hover:

Can confirm I am experiencing the same issue. I really want to see the histogram color coding that existed previously based on the bin weights.

I am also having exactly the same issue. Having back the usual histogram plots would be great

I also have the same issue and it has been there for a few days. Hope to get some feedback.

@JoanaMarieL I want to raise the same issue, my graph doesn't appear at all

When I move my cursor to the graph, it pops up the correct distribution

@JoanaMarieL is there any hope? There is plenty of gradient debugging to be done around the world, and everyone is waiting for the bug to be solved.

Hi everyone, this is tracked internally and will keep you guys informed for any updates.

Are there any updates on this? If not, is there a way to downgrade the UI to a previous version where the histogram still worked?

Also experiencing this, its pretty ugly for a pro 8000 duct im paying for to regress like this in core functionality.

For any histogram, I just see flat colours, before I used to see a heat distribution over values... Please fix asap. It kind of makes me want to use something else.

What I used to see:

Now what I see - just a flat colour, lots of information is lost!

@JoanaMarieL can you give an update?

Thank you for the follow up. We are still investigating this and we will get back to you once we received further updates from our Internal team. We do apologize for the inconvenience caused by this behavior.

I also have encountered the same problem.
I am hoping for a quick resolution as it is inconvenient when showing the results of experiments to my friends.

I checked with DevTools in my browser and it seems that the drawing of the histogram is done by the HeatmapSeriesCanvas class. (src/components/vis/HeatmapSeries.tsx)

The rgb(fillFunctor(d)) (d is an object like { x: 0, y: 1093.75, color: 0.25 }) is called to determine the color to draw the histogram bins, but it seems that the fillFunctor function always returns the same color. This seems to be the reason for the monochromatic rendering.

Since fillFunctor is a function obtained from getAttributeFunctor(props, 'color') defined in react-vis, specifying colorDomain as well as colorRange in props may help.

/* src/components/vis/LinePlotPlot.tsx */
...
          <HeatmapSeriesComponent
            key={i}
            colorRange={['#f0f0f0', line.color]}
            colorDomain={[0, Math.max(...line.data.map(o => o.color))]} // add this line
            data={line.data}
            size={2}
          />
...
