Boxplot generating flat lines no matter what i do

[niirex1]

My code gives me flat lines instead of a boxplot no matter what i do.

'''ggplot(testbp, aes(x = Dataset, y = Values, fill = Model)) +'''
'''geom_boxplot(varwidth = TRUE, alpha = 0.4)'''

Below image is the result of my code above with the flat lines

Below is my dataset i was working on

0	Metric	Values	Model	Dataset
1	Precision	98.74	BiLSTM	USTC-TFC2016
2	Precision	99.11	1D-CNN	USTC-TFC2016
3	Precision	98.96	LSTM	USTC-TFC2016
4	Precision	98.21	RNN	USTC-TFC2016
5	Precision	98.71	TCN	USTC-TFC2016
6	Precision	99.05	TCN-ELU	USTC-TFC2016
7	Precision	99.74	BiTCN	USTC-TFC2016
8	Precision	93.54	BiLSTM	CTU
9	Precision	94.20	1D-CNN	CTU
10	Precision	93.09	LSTM	CTU
11	Precision	93.39	RNN	CTU
12	Precision	94.33	TCN	CTU
13	Precision	94.82	TCN-ELU	CTU
14	Precision	95.59	BiTCN	CTU

Thanks for providing code. Could you kindly take further steps to make it easier for other forum users to help you? Share some representative data that will enable your code to run and show the problematic behaviour.

How do I share data for a reprex?

You might use tools such as the library datapasta, or the base function dput() to share a portion of data in code form, i.e. that can be copied from forum and pasted to R session.

Thank you. I have shared my dataset as requested

[nirgrahamuk]

the models per dataset are unique so there is no variation of values suitable for representing with a box

Edit:
You can try :

ggplot(testbp, 
aes(x = Dataset, y = Values)) +
geom_boxplot(varwidth = TRUE, alpha = 0.4)+
  geom_jitter(aes(color=Model))

Great. However, you try to generate boxplots from the "Model" based on the dataset. Because that is what i wanted to achieve.

Something like this below:

[nirgrahamuk]

therefore you should gather more data...

[niirex1]

Please explain further if possible. I don't seem to understand.

So i am analyzing a precision matrics with it's values per the models that were tested on the two datasets.

I feel that perhaps i need to restructure my data but i am new to the whole boxplot so i don't seem to know how to go about it.

Please assist any way that you can.

@niirex1

||BiLSTM|USTC-TFC2016

you only have one fact about this model and dataset; that fact is '98.74'
you need more than one fact to have a boxplot.
If you can only have one fact, then probably you shouldnt be using a boxplot...

[niirex1]

Ok. So how many do i need to be able to generate the boxplot?

[nirgrahamuk]

the absolute minimum, to see a box shape is two.

Many thanks for your help. I will add some more data, as indicated earlier.
