Grafana bar graph sorting, lower values not visible - grafana

I have a bar graph in Grafana (with InfluxDb). Its grouped by time and a tag. But I noticed that the large values are being drawn over the lower values.
Example below. You can see the points where the lower value bars are. I would expect that the lower values are drawn on top. Is this a setting?
Query:

Looking at your data it appears to be showing the time spent in each component of a request pipeline, so my suggestion would be to present them as stacked bars, which will better represent how each contributes to the total time spent.
You can enable stacked mode on the Display tab of the graph edit panel.
If you're more interested in seeing how each item compares to the others, then maybe a line or point plot would be easier to read, especially as superimposed bars will be be assumed to be stacked by most viewers.

Merging Percentage Lines with The Bars in Tableau Desktop

I have a graph that shows the ratio (count) of payable vs. processed words among the total words on stacked bars. I would also like to display the same ratio in percentages in lines overlapping the bars.
At the moment I have them in two separate graphs, but I want to merge them so that it takes less space in my dashboard view. I am unable to select the dual combination view as it requires two measures and even though I keep trying to cmd+click+drag the percentage measure pill to my marks, it's only changing the calculations in the bars but not allowing me to select the dual combination view.
Since the percentages are basically the ratio of the green/total in the bars, I don't think I need any complicated configurations for displaying it, however, I am also failing to achieve what I want.
Could you please tell me how to do this visualization?
Edit: I noticed that the reason I couldn't generate the dual combination view was that I had three date pills (year, quarter, month), and by removing two of them, I'm able to generate the dual combination view, but it's far from what I'm looking for as it's only splitting the stacked bar into bar+line.
Neeku, I certainly understand the desire to minimize "real estate" in your dashboard. If I understand your needs correctly, I believe that overlaying a transparent-background chart over the first chart might meet your needs, if a dual-axis chart doesn't work for you (for example, if you wanted to overlay a line chart on a column chart that is itself already dual axis).
By way of example, here is a simple Sample Superstore dashboard with a line chart on top and a stacked column at the bottom.
simple dashboard
Change the line chart to "Floating"
Size it to fit over your column chart and change the background to transparent by clicking anywhere in the line chart and select "Format"
...Format Shading
...and "None" for the color selection
Your line chart is now an overlay, but it's pretty messy.
Click on the line chart and hide field labels,
...turn off "Show Header" for each pill in the line chart
Clean things up and it should look better:
Note: one big issue with this approach is that you will not be able to click to select chart elements of the underlying chart.

Why does AWS CloudWatch dashboard widget does not respect scales when drawing two lines?

I'm new to AWS and CloudWatch.
Here is a screenshot of a CloudWatch dashboard showing two parameters related to a Dynamo table.
As you can see in the pop-up the value of the sample for the orange timeseries is 2,252 while the value of the sample for the red timeseries is 7,000, yet the red chart is drawn under the orange chart. If you check the scale on the left, it seems the red series is the one that get drawn correctly, while the line of the orange one is somehow "inflated".
Can you please help me understand what is the reason behind this?
It looks like your mouse hover point data and the popup data are out of sync. Just a UI glitch.
The popup is showing 09:57 and probably on the chart at 09:57 those are the correct values.
The hover point you chose is a particular peak and is at what time? The last digit is cut off from the display but it's definitely not a 7! Looks like "09:50" maybe?
Minor UI glitch is my diagnosis.
Eventually I come up with this different set up, where one of the series has values mapped on the left Y-axis, while the other series has values mapped on the right Y-axis.
The main drawback is that the two series are not directly comparable, but at least the difference in value is more evident.

How can I filter over a bar graph data while showing the average of the entire data set?

I am making an interactive dashboard in Tableau that looks something like this:
https://public.tableau.com/app/profile/monica.ionescu/viz/ExploringHIVStatisticsinSouthAmerica/Dashboard1?publish=yes
(for your best viewing experience, please view the dashboard in the fullscreen view - button on bottom right corner of the board)
I need some help with the bar chart.
I currently have a reference line in place to mark the two averages so that they don’t move as I filter through data. When using the average line feature, the filters on the left change all the graphs on the dashboard in real-time (and thus the average with it). So, it seems like the average line is built from the data points currently on display rather than all the data points in our data set.
I want to show the averages on the bar graph as they are in the image (a constant for the whole data set) without having to manually set the average each time I add/update the data.
How do I make it so that when I change the filters, the bar graph changes but the average stays constant?
Thank you so much!
You can self-blend the data sources - duplicate the data source, but DON'T join any fields/set up relationships. The lack of join can make the secondary source act as a constant.
Alternatively create a FIXED calculation to calculate the average. This should also act as a constant - just make sure none of your filters are in context.

Grafana stack line graph shows hidden series with value 0

I am using a stacked Grafana line graph and has given the option of hiding the series for values with zeros.
But yet there is a line drawn in the stacked series for a metric with value 0 (line colored in yellow). It is not shown in the legend as configured. It is not visible even in the tooltip.
Is there a way to hide the graph as well?
You can just set line width to 0.
This is due to the queries for different series happen one after another and there can be instances where the queries return a different number of data points.
The above issue can occur when some additional data gets written into the database in between queries and some series may not have values towards the end of the timestamps (null values). Therefore Grafana shows this as a drop in the series.
I had the same confusion recently with one of my dashboards. There is an open bug with Grafana to not draw the lines for the 0 values, during the time frame that they are zero, so as not to hide other lines with value underneath.

Tableau bar chart looks different in worksheet vs. dashboard

Trying to make a cute little dual axis line and bar chart, time is continuous on x axis, value on y axis. For some visual flair (formatting still being worked on) I wanted to make banded columns to show months, which are not calendar months (454 system) and are therefore variable lengths of time.
I got it functionally looking how I wanted to on the worksheet. When dragged to a dashboard, even after a ridiculous amount of resizing, I get these weird lines. When I change the size of it, the lines change places.
Anyone have tips on getting these two graphs to look the same?
