X-Axis as zero line in MPChart Line Chart - mpandroidchart

I am using MPAndroidChart library to show positive and negative values in Line Chart graph. I have enabled zero line using leftAxis.setDrawZeroLine(true). My question is can I show X-Axis in place of zero line? As in below example screenshot.
Thanks in advance

Gauge/ Scatter charts showing horizontal lines for large data at one point(qliksense limitation)

While working on Qliksense, Gauge/Scatter chart is showing horizontal line for large data at one point. Currently, the limitation is if there are more than 1000 data values at any given point in the scatter chart will show as horizontal line at one point. Is there any alternative way to resolve this issue for large data in Qliksense

PowerBI: Formatting totals on combined stacked bar & line graph

I have a visualization (below) that is a combination Stack bar and Line graph . I am trying to format the data labels for the line graph totals- so that they all hover above the stacked bar. This works(with default settings) for all of the dates except the first bar (see image below- highlighted in yellow). There appears to be no formatting options available for the data labels of the line graph to control the label position (unlike in the stacked bar).
Any suggestions on how to force the totals to always appear above the bars?
A simple example file is available here https://drive.google.com/file/d/1m4qicc5gv5fCmVPiBe2m6THuHGKjacnx/view?usp=sharing
Any suggestions appreciated.
Go to Format > Y-Axis > Show secondary and set it to the Off position and it should look like this:
What's happening is that your line and bars were on independent axes, which makes them align not how you intend.
PowerBI supports Total labels for stacked visuals:
You can now turn on total labels for your stacked bar/column, stacked area, and line and stacked column charts, allowing you to see the aggregates of your data at a glance

Optimal display for overlapping series in a line chart

In a context of a line chart displaying time data in regular intervals where multiple series might overlap what would be the optimal way to:
A) hint the user that the chart has overlapping series?
B) give the user the capability to visualize all those series? Like spanning the series somehow?
For overlapping series in a line chart, I would keep the traditional line chart but put a label at the end of the graph with a color legend. The legend and label will help the user get information quickly.
Another version of a line chart for overlapping series can be a line area chat.
If you are not stuck on only line charts, I would suggest a bar chart. Below are some examples that you can use.
Example 1:
Example 2:
Example 3:
There are couple ways to indicate that there are overlapping series on a chart. You can increase the marker radius of one of them. The number of legend elements tells you how many series there is, too. Finally, you can distribute series on a different yAxis, with different top and height properties. Also, in styled mode, when you hover on legend item, other series opacity changes.

Core Plot - adding a vertical/horizontal line indicator on a selected value point

I am using core plot to make a line graph for my iPhone app. So far I successfully made the line graph from my xml data.
Furthermore I added a text layer that shows the value (for example 40) once I select the cell
holding the value 40. For this, I use the function:
(CPTLayer *)dataLabelForPlot:(CPTPlot *)plot recordIndex:(NSUInteger)index
So now I want to have a vertical line on the graph to indicate the selected value (the 40). I tried adding CPTBarplot but somehow the bars show only at the beginning of the graph axis.
Is there a function from core plot like the above that will create a line indicator?
I would appreciate if someone can give me some hint how to solve this problem and thank you very much in advance.
You could use a scatter plot for that. There's a point selection demo in the Mac CPTTestApp that draws a crosshair over the selected point. It would be trivial to modify that to only draw the vertical line.
The -numberOfRecordsForPlot: datasource method returns the number of points in the selection indicator (5 for the crosshairs) or zero (0) if there is no current selection. The -numberForPlot:field:recordIndex: method returns the points in the indicator. The points are drawn in this order:
Left
Right
Center (with plot symbol)
Top
Bottom
The -symbolForScatterPlot:recordIndex: method controls the plot symbol in the center. You can eliminate this method if you don't need any symbols on the indicator plot.

How to change text of y-axes on a matplotlib generated picture

The page is
"http://matplotlib.sourceforge.net/examples/pylab_examples/histogram_demo_extended.html"
Let's look at the y-axis, the numbers there do not make any sense, could we change it to something else that is meaningful?
Except the cumulative distribution plot, and the last one, the rest of the y-axes data show normalized histogram values with normed=1 keyword set (i.e., the are underneath the histogram equals to 1 as in the definition of a probability density function (PDF))
You can use yticks(), see this example.
