I am trying to create a medical graph to display the heart rate. It will have the live data on the left part and the prediction forecast on the right. I will get both from the backend API, and I need now to show them as one line on the graph. I am using ReactJs and chart.JS.
Look the picture below to understand better:

I just tried to do the regression but it will be done from the backend. I am getting from the API two fields: live data: and prediction:
And I need them to add them together.
I think you can use segment option for this. You can change line styles based on datapoint options / value.
Usage example: Link an official example

I'm trying to plotting multiple lines in one single graph. I've combined two of them using dual axis, but I don't know how should I add another.
Thank you in advance for any help.
Since you have mentioned that you want to show multiple measures in one viz it means that one axis is sufficient for all these measures. Therefore, Instead of creating dual axis chart, do it like this-
Step-1 Build line chart with one measure.
Step-2 Drop another measure on the axis directly instead of rows/column shelf where you'll see a double bar icon like the screenshot.
step-3 Drop additional mesaures either in similar ways or onto measure values pane created automatically. See a demonstration screenshot below on sample superstore
I'm currently working on my bachelor's thesis and I am trying to work with Sentinel 5 - P's aerosol data.
I am trying to obtain Aerosol Layer Height (L3__AER_LH) data but I do not know the bands, which I need to 'select'.
The README file on L3__AER_LH reads as follows:
The data file contains the aerosol_mid_pressure and aerosol_mid_height which provide the
air pressure at the center of the aerosol layer and the height at the center of the aerosol layer relative
to the geoid, respectively.
But when I try running: .select('absorbing_aerosol_index'); I get no results.
Therefore, I have tried using print(collection.bandNames); but I recieve an 'undefined'.
Could someone help me obtain L3__AER_LH data from GEE?
Thank you for your time.
Therefore, I have tried using print(collection.bandNames); but I recieve an 'undefined'.
The best way to find out about bands programmatically is to look at the band names of one image, because band information for a collection is sometimes incomplete.
print(collection.first().bandNames());
That said, for datasets from the Earth Engine Data Catalog, you'll get documentation as well as the names by looking at their catalog pages (example), so doing so is a better option in that case.
That page tells you that the band names for L3_AER_LH (as provided by Earth Engine) include aerosol_pressure and aerosol_height.
I have two values I wish to plot against each other in tableau. They are two totals aggregated around the same date. I can get them to the point where they are plotted on a dual access against the date like so:
but any attempt to plot them against each other for correlation has come to nothing. I've tried simple conversion to scatterplot, using calculated fields, using a cross tab with subtitles and attempting to only plot the subtotals against each other all of which have failed. I could do it in Excel but have to do it in tableau.
I have consulted the official Tableau 9.0 guide, google and existing questions on Stack Overflow all to no avail. If I was doing this in BOXI, I could just select the columns and chart them. How do I do the equivalent visualisation in Tableau?
You aren't clear about what type of chart you want to make.
Do you want a scatter plot? If so, put one measure on the row shelf, the other measure on the column shelf, and one or more dimensions (such as your date) on the detail shelf to define how finely to aggregate the data. Check the aggregation functions you use (SUM, AVG) and the aggregation level for your date fields (YEAR, MONTH ...) as desired. You probably want to use the second block of date aggregations on the menu unless you want to group all January data together regardless of year.
If you want a connected scatter plot, set the mark type from automatic to line and move the date field from the detail to the path shelf. You might also then want to put the date on size, color or legend to visually show the direction of time on the line. You might need to change that field to attribute in some cases to avoid creating multiple lines.
Tableau is fantastic once you learn how it works, and get a strong understanding of how choices about treating fields as dimensions or measures, or discrete or continuous impacts the behavior. If you skim over those details, you can still make beautiful charts by following recipes, mimicking examples (and asking StackOverflow), but Tableau's behavior will seem mysterious and arbitrary.
If you take some time to learn the fundamentals about how Tableau works, it will repay your time investment. I recommend Joshua Milligan's book Learning Tableau for a good way to start, along with the training videos on the Tableau website.
I have a crossfilter.dimension. How do I get the current filter set on it (for example if it was set by a brush from a chart)?
Example:
dimension.filterRange([1,15]) // returns dimension
Given this filtered dimension, how do I get the values 1 and 15 out?
Stumbled on this old question because it is the top-voted unanswered crossfilter question, with 1k views!
This feature was contributed by Thomas Gillet in 1.4.5 as dimension.currentFilter()
The tough remaining problem: when you get beyond filterExact and filterRange, the more complex filters use filterFunction. You might be able to retrieve the function but functions are essentially opaque.
For example, if you are using dc.js, it will generate a filter function when
multiple items are selected in pie chart, row chart, or bar chart with ordinal dimension
the chart has a two-dimensional filter, like the scatter plot or the heatmap
For this reason, if you're using dc.js, you should use chart.filters() instead.
Thank you, Gordon. This was really helpful to me! One note - your link is correct -- it goes to filters(), but the text displays as chart.filter() which is in the API, but doesn't return multiple filters on a chart. I tried to edit your answer, but it won't allow single character changes!
I use Jenkins and its Plot Plugin to generate statistics.
Example:
For every Build I plot the line of codes. Lets say I have like 500.000 lines and it changes about +-100 lines per build.
Since the plot y-axis always starts with 0 the whole plot is meaningless. It looks like 1 straight line.
Same goes for other metrics, if the value is too high.
Question: is there any configuration to set minimum y-axes to the minimum value?
Unfortunately, I think the answer to your question is currently 'no'.
First of all, the documentation does not give any hints towards such an option.
Secondly, Given that the Jenkins Plot Plugin uses JFreeChart for the plotting, the setting of a range for the Y-axis should be done using the 'getRangeAxis' function. A search in the source-code does not reveal a call to this function.
Lastly, you do not seem to be the only one that has this problem. Issue JENKINS-2841 asks for the same functionality, but appears not be solved yet.
