QUESTION
For a project, I'm trying to plot on the same figure (using subplots) to "graph". The data have been collected using a database (but for my problem here, I tried to selected only reasonable number of value).
On the left of the figure, I plot the temperature in JFK during 10 consecutive days whereas on the right, I plot a scatter of the temperature in various locations in the US on a specific day.
This is the part where it gets tricky : I'd like to use a colormap to display the variation of the temperature across the country and even if I've been able to change the color of the colormap, the dots of the scatter are all with the same color
Here are my variables:
...ANSWER
Answered 2021-Jun-11 at 06:21Thanks to @JohanC, I've been able to fix my issues:
Using scatter1=ax[1].scatter(longitude,latitude,cmap='RdBu',s=20) and fig.colorbar(scatter1, ax=ax[1], pad=0) have help ensuring the colorbar was not overflowing below the graph. This is what I get when I'm inserting these line in my code :
Then, by working on the code by my self, I realized that in order to have the dots in different colors depending on the temperature, I could 'simply' remove the line cmap = plt.cm.RdBu and, change in the scatter function (scatter1=) the value to temp: scatter1=ax[1].scatter(longitude,latitude,c=temp,s=20)
QUESTION
I'm trying to import some buys and sales into the chart. Ideally I would like to mark the candle and show the amount but I have two issues.
The first is that I keep getting "Array is too large. Maximum size is 100000" When I add many trades ( around 50 ) and the second is that I don't know how to display the amount.
I googled around and this is the code I managed to write but as mentioned is not working.
Is not a long or short strategy, I just need to move buys and sells into the chart
...ANSWER
Answered 2021-Jun-10 at 21:51You're exceeding the array limit because every bar you're unnecessarily adding the trade data to the arrays every bar. With the var array, you only need to do it once. Either nest the add_trade() calls in if barstate.isfirst or use array.from()
var int[] when_buy = array.from(timestamp('2021-06-01'), timestamp('2021-05-27'), etc....)
To display the amounts use label.new()
QUESTION
I make 3d plots with matplotlib and I always get a weird frame with a normalized scale around my plot. Where does it come from and how can I get rid of it ?
Here is an example code that drives me to the problem :
...ANSWER
Answered 2021-Jun-10 at 13:39You call plt.subplots(...) and this, of course, instantiates an Axes, complete of horizontal and vertical spines, before Matplotlib is informed that you want a 3D enabled Axes.
When you later call plt.gca(...) it's too late…
Simply use

QUESTION
I just began learning python and interactive plotting, so any help is welcome.
The purpose of this code is to click on one of the ten buttons to choose a value between -5 and 5 and then display this value by clicking anywhere on the main axis to then generate an electric field map from these points. The problem is that when I click on any button, a dot is plotted in the middle of the graph. If i understood correctly what was happening, the onclick function interprets the axis of each button as a part of the main axis. Could someone help me solve this problem please?
...ANSWER
Answered 2021-Jun-07 at 17:51Welcome, and welcome to Python.
I am sure I do not have the best answer, as I have not used canvas.mpl_connect, but I believe I have one solution for you.
Put all of onclick(events) under an if statement so that clicking the buttons (Subplots, not the main Axes) does not trigger everything:
QUESTION
This has been asked before but I havent found any working solution for me. I have been trying to figure out how to change default font in Matplotlib plot to Lato.
There are several posts/threads out there, e.g. 1, 2, 3. With these posts, I tried building up as following. Firstly, all fonts from my computer are added to font manager, like suggested in example 2.
...ANSWER
Answered 2021-Jun-06 at 21:24With that font, it is better to install all of the family (or at least the main styles). Keep in mind that Lato is a sans-serif font and since you want to use it as the default font for all the plot (for just one script), it should be in the sans-serif family option.
QUESTION
Matplotlib madness...
...ANSWER
Answered 2021-Jun-05 at 03:37It's not flattening it per se. But the scale of the second line/plot is much bigger than the first that it shows like it's flattened.
You will need to use multiple scales (multiple y axis).
Check out this example from the matplotlib documentation.
Basically, you will need to do something like this:
QUESTION
Here I've allowed numbers to be entered as a string which is then converted into a list, and at the end I have set x and y to be empty lists again, but it outputs a graph using data values from each iteration so that there are 3 different lines on the graph output, instead of just one.
...ANSWER
Answered 2021-Jun-03 at 21:38You are plotting into the same figure. Clear the figure with plt.clf().

hi i need get baseline price and show with Hline in chart(idont need chart price(close,low...) just i need icimoku baseline price) this is my code
my error: line 10: Cannot call 'hline' with 'price'=series[float]. The argument should be of type: input float
code:
...ANSWER
Answered 2021-May-23 at 20:26hline() can't accept a series types such as close or bs which change from bar to bar, only a static input value or set value such as hline(30)
You can use trackprice = true with plot()
QUESTION
I am new to pine script coding. I am just trying to plot the previous day's high and the previous day's low in the current day's level. It seems to draw/plot correctly for the rest of the day candles, but the levels/lines are missed on the first candle of the current day. How can that be corrected?
The levels seem to be drawn correctly after the first candle. Same is the case with stepline as well.
Below is my pinescript code
...ANSWER
Answered 2021-May-29 at 15:37study("BNiftyLevels", "BNL", overlay=true)
[h,l] = security(syminfo.ticker, "D", [high,low])
plot(h, style=plot.style_stepline, color=color.red, linewidth=2)
plot(l, style=plot.style_stepline, color=color.green, linewidth=2)
