I tried the following code in my script, but it doesn't work, becuase of error: Cannot use 'plotshape' in local scope.
for i = 0 to counter_buy
plotshape(high + counter_buy, style = shape.circle, location=location.absolute, color = color.green, size = size.auto)
What I'm trying to do:
There is a counter in my script (counter_buy) I want to draw a circle for each value of "1" above the current bar. So if the counter is "3" I want to draw 3 circles above the current bar. Each circle above the other, like this example:
o
o
o
BAR
Is there a way to archive this?
Thanks, Mag
You can't use plot statements in for loops or any other local block in a script. There are 2 ways to go about this, depending on your requirements: either with multiple plotshape() calls or with labels.
Is it important that you see those circles on ALL the dataset's bars where they should appear or are you OK with only the last ~50 occurrences showing?
What's the max value for counter_buy?
thanks for your response. My solution were counters in my script that gets higher or lower at specific situations, like crossovers. Then I plot arrows above or below the current bar, with values of my counters.
plotarrow(counter1, colorup=color.green, colordown=color.red, transp=30, maxheight=50)
plotarrow(counter2, colorup=color.blue, colordown=color.blue, transp=30, maxheight=30)

I am trying to create horizontal bar chart in in R using the plotly package. Due to the length of the legend items I would like for them to show horizontally at the top or bottom of the visual in 2 columns. Is it possible to dictate the number of columns for the legend?
I've been able to place the legend below the x axis successfully using Layout(legend = list(orientation='h')) however regardless of where I put the legend (using the x and y arguments) it is always just one long list. I've seen a github project for creating a multi column legend in js but not r.
Thanks,
This is not possible in a normal way. I think it has its own logic that determines how many place there it is and how many columns it will display then.
So I guess if you make your plot width smaller you could reach the goal that it will just display 2 column.
Also you can try to play around with the margin attribute (https://plot.ly/r/reference/#layout-margin) by setting r and l to 10 e.g.
An other idea could be to make the font-size in legend (https://plot.ly/r/reference/#layout-legend-font-size) bigger, so that it just uses two columns. Hope it helps.
I read the same github page and I thought that it is not possible, but seems to be! I only checked in Python, but I hope this will help in your endeavors in R as well as everyone in Python looking for information. Sadly, there is not a lot of information on Plotly here compared to other packages.
This solved my problem
Setting orientation='h' is not enough. You also have to put the legend items in different legendgroups, if you want them in different columns. Here is an example with legend labels:
fig = go.Figure([
go.Scatter(x=best_neurons_df['Test Size'],
y=best_neurons_df['Training Accuracy Max'],
# You can write anything as the group name, as long as it's different.
legendgroup="group2",
name='Training',
mode='markers',
go.Scatter(x=best_neurons_df['Test Size'],
y=best_neurons_df['Validation Accuracy Max'],
# You can write anything as the group name, as long as it's different.
legendgroup="group1",
layout=dict(title='Best Model Dependency on Validation Split',
xaxis=dict(title='Validation Set proportion'),
yaxis=dict(title='Accuracy'),
margin=dict(b=100, t=100, l=0, r=0),
legend=dict(x=1, y=1.01,xanchor='right', yanchor='bottom',
title='',
orientation='h', # Remember this as well.
bordercolor='black',
borderwidth=1
))

When a graph is very wide I want to show the y-axis values also on the right side of the graph so it becomes easier to read the corresponding values of the lines.
I know how to duplicate the left axis to the right. And when the graph is created I use ActYscl to set the range of scale nr 0 (left) to scale nr 1 (right). This works when the graph is created and also the zoom and pan function work on both y-scales. However, when I use the Autoscale function of the Graph Pallet, only the initial axis is scaled (probably because the graph data are only linked to the original axis).
Is there a way to make the autoscale function work for both y-axis at the same time?
Charts and graphs have an Autoscale Range Change event. Use an event structure to catch this event and update the range of the duplicate scale to match the first one:
I've used a chart for this example as it's simpler, but it should work the same for a graph. Of course you need a way of telling the event loop when to exit; I've used the Value Changed event of the stop button. If your application uses an event-driven structure anyway, you should just be able to add the autoscale event to your existing event loop.
I am trying to create a colorplot using pcolor. I want to use "shading interp" so am not using imagesc(). However when I set the axis manually the plot has white space between the data and the axis.
I want to zoom into one section of the data rather than the whole image. (This problem does not occur when the matrix and using "axis("tight") )
Thank you in advance for your help
The code I am using is :
clf
load x.dat;
load y.dat;
load 15-1-14_E2_lam_7410nm.txt
x=x;
y=y;
A=X15_1_14_E2_lam_7410nm;
A=rot90(A);
h=pcolor(x,y,A);
shading interp
set(h,"EdgeColor",'none');
axis([60 90 -20 20])
#axis("tight")
colorbar
I believe the white space at one or more axis edges is because your data does not go fully to the edge of the frame (or the axis) you are setting. This can happen frequently when using something like meshgrid() to set the frame from -L to L in steps dl but then your data may start at -L and only go to, say, L-dl.
I have a real-time line chart. For that I use TimeSeries. Now I get new values every second. But I don’t want to get a x-axis line every second. I like to get one every ten seconds.
So maybe, first it would be important to know where the x-axis lines were painted. Is it xymultipleseriesdataset.addSereies(timeSeries)? So maybe I can create a loop that add every 10 second a new title for the x-Axis... or am I totally wrong?
If I am right, you are asking for a way to control which labels are shown on the x-axis.
To do that, you may use the XYMultipleSeriesRenderer.addXTextLabel(timeInMillis, "requiredlabel").
This will cause the automatic generation of labels to stop and you can then have complete control on which labels are shown and which are not.
Edit:
Seems like I was wrong about automatic generation of labels stopping.
Use the method XYMultipleSeriesRenderer.setXLabels(0) to stop the generation of labels. This method is used to set how many labels should be generated for the x axis. Passing 0 should stop automatic labels to stop altogether.
When making a line chart, Lets say its for business sales for different depts and horizontally is days and vertically is dollars. When you hover over a line it tells a dataTip tells you the sales for that dept. on that day. I want it to show all the depts at the same time, so say you hover over day 3, I want the dataTips for all depts on day 3 to display so you can compare the values for all the sales on the same day. I set the mouseSensitivity for the dataTips to display all the lines at once but I end up getting day 2 for one dept and day 3 for another which is not wanted. This is actually posted as a bug and explained better here: http://bugs.adobe.com/jira/browse/FLEXDMV-1853
I am wondering if anyone can come up with a work-around for this?
Thanks!
I ran into a similar problem to this recently and came up with a solution that also applies to your problem. I had a step LineChart and wanted to display a data tip when the user hovered anywhere on the line instead of just at defined data points.
You can read about the solution I wrote for that problem here: Flex: Customizing data tip location and behavior in a LineChart
You'll have to modify my solution slightly to fit your problem:
On line 47 you can remove the Math.abs(last.y - mouseLoc.y) < 50 check. This constrains the data tips to lines that are within 50 pixels vertically of the mouse.
I'm assuming that you're using the default segment line chart which just draws lines directly between data points. You'll need to modify the code that calculates the line value at a given x-coordinate to work with that chart type. I already find the closest data point to the left of the mouse with lines 33-41 and store it in last. Just get the next data point (which will be the one closest to the right of the mouse) and use something like this to get the value at the mouse:
var slope:Number = (nextPoint.y - last.y) / (nextPoint.x - last.x);
var lineYAtMouse:Number = (slope * (last.x - mouseLoc.x)) + last.y;
var lineValue:Array = line.localToData(new Point(mouseLoc.x, lineYAtMouse));
Then replace lines 69 through 72 with:
hitPoint.x = mouseLoc.x;
hitPoint.y = lineYAtMouse;
hitPoint.xValue = lineValue[0];
hitPoint.yValue = lineValue[1];
I haven't tested these modifications so there could be a bug or 2 but the general idea is there. I hope maybe this is still useful to someone. This question is getting pretty old. :)
Not an answer, but a poor alternative:
You could create your own DataTip renderer that [ahem] mapped the location of every point and drew the tip for each one there.
Basically, you would be duplicating a lot of the code inside the charting classes.
I have the same problem but working on column charts. Was thinking that I could enable the vertical gridLines using backgroundElements and then add a chart event listener for mouse over (which fires when mouse passes over a vertical gridline). Using the localX value, i could compare it to the closest datapoint, maybe.
