I have a stackplot in Excel as shown below. I'm trying to generate the same plot using Python.

My code for the same is below.

x = ['d1','d2','d3','d4','d5']
labels = ['a','b','c','d','e']
sns.set(font_scale = 1.25)
plt.stackplot(x,gA,gB,gC,gD,gE,labels=labels) #gA,...,gE stores the percentage values
plt.legend(loc='upper left')
plt.title('Reason')
plt.show()

A sample y - gB looks like below

+---+--------+
|   | Reason |
+---+--------+
| a |      4 |
| b |     32 |
| c |      4 |
| d |     56 |
| e |      4 |
+---+--------+

I get a really strange plot when I run this.

What am I missing out?

Your question is not [replicable](https://stackoverflow.com/questions/20109391/how-to-make-good-reproducible-pandas-examples). Why don't you share `gA,gB...`? – Quang Hoang Jun 11 '19 at 16:52
Why not use pandas `df.plot.bar(stacked=True)`? – cs95 Jun 11 '19 at 16:53
@QuangHoang: Please feel free to use gB for all other g's for demonstration purposes. – srkdb Jun 11 '19 at 17:00
@cs95: I want an area chart. the stacked bar won't give continuity – srkdb Jun 11 '19 at 17:01

Ah, meant [`plot.area(stacked=True)`](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.plot.area.html) – cs95 Jun 11 '19 at 17:02
@cs95: I think this'd work. I'll try this. If you can do with the stackplot, let me know. – srkdb Jun 11 '19 at 17:34
I would but I don't have your data, unfortunately. – cs95 Jun 11 '19 at 17:40
@cs95: What other data do you need? – srkdb Jun 11 '19 at 17:45
Preferably gA-gE? – cs95 Jun 11 '19 at 17:47
As I mentioned above, please use gB for all gA-gE. – srkdb Jun 11 '19 at 17:51
With the `gB` provided, the 2nd picture is correct for stack plot. The first plot is relative (all capped at 100%). Is that what you want? If so, @cs95's area plot is the answer. – Quang Hoang Jun 11 '19 at 18:36
