I would like to set the gap between each bar inside this example to a fixed max number.
So no matter how many bars are present in the polar, the gap should never be larger than 12px. Actually I tried to use the barGap prop, but this does not work.
I'm trying to build an app that has just a single portrait oriented view. There is a title on top and results label at the bottom of the view, these are locked to top and bottom and center, no problem here.
Now this is the tricky part. I have 9 rows of labels, most single row but couple span out to 2 rows. I want them to spread out evenly between the title and the result-label.
I lock the first label to top-left, lock the leading edges and then set equal vertical distance constraints between the labels. Otherwise ok but the last labels on 3.5 inch display overrun my results -label.
So I adjust either the fontsize or make vertical distance between labels smaller or both. 3.5 inch problem fixed but now there is a big empty gap between the last label and result. On iPhone 6 its really ugly.
I have tried all sorts of methods but can't just get this working.
So basically: how do I reserve 10 % of view height from top and 20 % from bottom and tell Xcode to use the rest 70 % (and all of it) for my 9 rows of label, evenly?
Thanks for help!
Would have posted an image but no rank for such things...
If I understand you right, you need several flexible spaces that will all be the same size. One space in-between each of the labels.
Create UIViews to put between each label, set them all to have equal widths or heights and anchor each one to the views it is supposed to sit between.
I got this idea from another SO question: Springs in Auto Layout: Distribute views evenly, with constraints, in Xcode 5
I've been working on adapting the stacked bar chart example (http://bl.ocks.org/mbostock/1134768). The problem I'm having is that there's
always outerpadding. The API lists the outer padding as a 3rd option, but omitting
it or setting it to 0 still leaves some padding. In most cases, it isn't too bad,
but with large data sets it tends to be a huge amount of padding. For all the code
relevant to my issue, you can check the link above. It's not very noticeable in that
example, but the first bar isn't drawn until about 12 pixels (in larger data sets I'm using
this can be at 100 or more pixels); I want it to start at 0 pixels.
Thanks! If you need any more explanation just let me know and I'll do my best.
EDIT: After testing, it appears rangeBands() starts at 0, but I'm still not sure why the rounding
from round bands would round as much as it did. Oh well, I can deal with using rangeBands.
I want to create a vertical bar plot. This is my code:
bar (x, sensiv);
title ('Promedio X')
xlabel('Nm')
ylabel('Refl.')
The problem is it looks like a stair plot. I've tried to add (x,sensiv, 'stacked') but it doesn't work. It looks grouped, as you can see in the next image:

I think it's because of x-axis but I couldn't change it. How can I do it? Does somebody knows how can I do it?
EDIT
Thanks Colin! I've tried to zoom and I understand what you mean and I've tried with different values, as slayton and you said.
I think that maybe it's the way I've code the plot, it is possible?
abc=0;
for p=(61:201)
abc(p)=out1_c;
end
for p=(151:301)
abc(p)=out2_c;
end
for p=(231:380)
abc(p)=out3_c;
end
for p=(381:596)
abc(p)=out4_c;
end
for p=(1152:1531)
abc(p)=out5_c;
end
for p=(1651:2051)
abc(p)=out7_c;
end
for p=(2052:2151)
abc(p)= 0;
end
The default value for the width of the bars in a bar plot is 0.8, so given that you're not currently specifying the width, you should have gaps in between each bar. This is going to sound really obvious, but have you tried zooming in on the bar plot that is created? For some datasets, the bar function will return a plot that looks like a stair plot, but in fact has gaps if you zoom in far enough. If this is the case, then you should be able to get the gaps you want by tinkering with the width parameter as suggested by slayton.
EDIT
Okay. First things first. If you want to post additional information, you should add it to your question, NOT post it as a new answer! You can do this by clicking the edit button just below where your question is on the page. To make things more readable, you might preface your edit with a capitalized bold-face heading "EDIT" as I have done here. If you are able, try now to move the additional information you've given back into your question, and then delete the answer.
Second, I have to be honest, the additional information you posted was somewhat confusing. However, I think I understand what you want now. You want 7 bars coming up to the heights out1_c, out2_c, ..., out7_c (variable names taken from your additional information) with a small gap between each bar, and the x-axis to reflect (approximately) the intervals 450-550, 550-650, etc.
Well, if you want 7 bars, then you want your input to only have seven elements. Set:
y = [out1_c; out2_c; out3_c; out4_c; out5_c; out6_c; out7_c];
y now gives you the heights your bars will come up to on the y-axis. To locate the bars on the x-axis, define a vector x that also has seven elements, where each element gives the midpoint of where you want the bar to be on the x-axis. For example:
x = [100; 200; 300; 400; 500; 600; 700];
Then just use bar(x, y). This should get you started.
A final point on the code you posted, you can actually completely avoid the loops: read up on vectorization. But if you are going to insist on loops, the first and most important rule is to preallocate your vectors/matrices. In your code abc starts out as a scalar (a 1 by 1 matrix), but then for every p, you are adding an element at index p. What is actually happening in the background is for every p, matlab is scrapping the current abc you have in memory, and building it again from scratch with the additional element. As you might expect, this will slow down your code by many orders of magnitude.
You can set the width of the individual bars by passing a value between 0 and 1 to bar. Passing 1 indicates that there should be no space between the bars
bar(x,y,1)
Passing anything less than 1 will reduce the bar sizes and introduce spacing between the individual bars
bar(x,y,.5)
I want to display overlapping boxplots using Sigmaplot 12. When I choose the scale for the x-axis as linear then the boxes do indeed overlap but are much too thin. See figure below. Of course they should be much wider.
When I choose the scale of the x-axis to be "category", then the boxes have the right width, but are arranged along each single x-value.
I want the position as in figure 1 and the width as in figure 2. I tried to resize the box in figure 1 but when I choose 100% in "bar width" than it still looks like Figure 1.
many thanks!
okay, I found the answer myself. In Sigmaplot, there is often the need to prepare "style"-columns, for example if you want to color your barcharts, you need a column that holds the specific color names.
For my boxplot example I needed a column that has the values for "width". These had to be quite large (2000) in order to have an effect. Why ? I have no idea. First I thought it would be because of the latitude values and that the program interprets the point as "1.000"s, but when I changed to values without decimals, it didn´t get better.
Well, here is the result in color.
Have fun !
