Candlestck and OHLC chart in Annotated Timeline, Google Visualization - google-visualization

Is it possible to draw candlestick and OHLC charts on Annotated time line now? Or any announcement about this. Since Google finance already has all the features.

As you can read here: http://groups.google.com/group/google-visualization-api/msg/8187f49dee43d311
no, but it will be there soon(tm) :)

chart.js issue with display between two charts with same code

I'm having an issue with data vertically too close together in the first chart while the other is not.
Chart With Issues
Chart Without Issues
Transition between charts (scroll down halfway)
Actual Chart to view: http://www.ironclads.com/temp/chart.html
As you can see from the images the text and corresponding chart values are compressed together in the first chart but look ok in the second.
The code is the same and the values in the first chart are 1000, while the second chart is 703. Is this why it compresses the first chart values? If so, is there anything I can do programmatically to resolve the issue between charts or am I on the right track that I just need to get the entry count closer to the same in order for the two charts to look the same?
I'm attaching the code to the html chart file in question as a link below. I also try to limit the number of entries to 1000 or less per chart in order for them to not break the browser or the chart.
Any ideas you have or suggestions are greatly appreciated. Thank you.

Ok folks. Figured it out with some help elsewhere. It appears a sub wrapper is in order, along with changing that subwrappper to fit. Here's the link to the fixed chart, you can compare the first with this and see the changes.

I am looking to plot a Line Chart (of Temperature vs Timestamp) in Google Data Studio

I am working on Google Cloud Platform and I am using the IoT related services available there. But, to plot a line chart of temperature vs ts (timestamp) in Google Data studio, with the data from Google Cloud BigQuery, I am facing the following issue:
My data:
What I wanted to plot: (It's done in Google excel sheets):
What I am getting:
Basically, in Datastudio I am able to plot, only the average of all data points available. I am not able to plot with respect to "minute axis", other than for a day-wise average plot. Please help me fix this
Thanks in advance
this is what i did, it is a workaround but it works in my case
copy timestamp and format it as hh, rename it hr
make another copy of timestamp and format it as mm, rename it as minute
add new calculated field and use this formula
CAST(CONCAT(datetime,hr,minute) AS NUMBER)
edit : more context
data studio support only YYYMMDDHH , the lowest level of details is day-hour, if you want to show day- hour-minute, you need to create a new calculated field, it has to be string or number ( I prefer number, as I want to do some calculation on the date).
all I am doing is creating a number that look like this 201908121400, and use it in my chart
edit : 22-Aug-2019, DS support it now, not need for a workaround

PowerBI How to add a trend curve to the graph?

Is it possible to add a trend line to graph in Power BI ?
For example like in excel
Now is possible to add a trend line, but it is a very basic one; in Excel you can put a polinomial trend line for example.. is very strange that Excel is much better than Power Bi in some cases..
Unfortunately, at the moment it is not possible. However, you can vote here for Microsoft to add this feature in feature releases.

Can Power BI add range selection to a Line Chart?

I'd like to build a report with power BI line chart. For there are too many values on the X-Axis, I was trying to add a range selection on the X-Axis like what amChart does.
So, I'm wondering if power BI can do this.
Also, I want to add hyperlink to each value on the X-Axis to link to related shared folder, is it doable?
For time range selection, take a look at https://app.powerbi.com/visuals and try the Advanced Time Slicer visual. It might already do what you're looking for.
For the x-axis urls, you have several approaches you can try. The easiest approach is to have a related table in your report that shows the links. Then when a user selects a datapoint in your line chart, the table would update to show the relevant links. Alternately you might try to extend the Power BI line chart with your own logic. This might be hard since Cartesian charts are more complex than other charts. You can find the line chart code here: https://github.com/Microsoft/PowerBI-visuals/blob/master/src/Clients/Visuals/cartesian/lineChart.ts
Alternately you can just write your own purpose built visual that does exactly what you want. This might actually be easier than extending the Power BI chart. You can learn how to build your own visual by looking at our wiki: https://github.com/Microsoft/PowerBI-visuals/wiki
I was thinking about this more and wanted to mention one more solution. If you're looking to show the 'last n days' of data, instead of an arbitrary range, you can add a measure in DAX that returns the last days. I have an example here: http://blogs.msdn.com/b/lukaszp/archive/2015/08/08/finding-the-latest-date-in-power-bi-desktop.aspx

How to overlay a line plot over a bar graph in APEX?

Right now I have a stacked bar graph and a line graph on one page using apex 'create a region' functionality. I'd like to combine these to one chart. I am thinking if you pehaps create a custom xml code in order to do so, but i'm not sure if that's the right direction to go to. Any help in this regard is appreciated.
No need to fiddle with XML. Create a second series in the chart using the SQL of your second chart and set the 'Series type' attribute to 'Line'.
Check "Multiple Y-Axis" in the display settings to plot your second series with a separate set of Y values. This means the number range offered in both series can be different scales. This can rescale as you show/hide specific series, as offered in one of the Legend properties.
Here is a link to a sample application by Hilary from the APEX team, plenty of examples in there regarding what is possible:
