"cannot convert text to date type" dddd, hh:mm:ss

[aarola]

I am using formula format (date, "dddd, hh:mm:ss"). Seems like this custom format is not accepted as date type, so I can only get it as a text. If I try to set it as a date type, I am getting error "cannot convert text to date type".

Is it possible to add additional date formats? 

Since Power BI only takes it as text, this is the resulting x-axis graph...

Power BI tries to show all of the points (15 min over 1 week), which is not possible to fit in any graph. As far as I know, that would be solved if it was a date type axis.

Any ideas? Thanks!

Still didn't get any valid solution. Found another example, someone trying to do something quite similar:

https://www.reddit.com/r/PowerBI/comments/7f60kg/how_to_get_cumulative_line_chart_with_monthday_on/

Tried applying hierarchy, didn't work, axis does not autoscale:

Tried with a "time index", so that axis is a whole number, defining a continuous value for each axis point, but then you don't have a clue of axis position (day? time?):

Tried increasing page size, but visuals do not scale properly.

Would it be possible to create a custom line chart visual which allows to do something like this? Any other options?

Thank you everyone involved.

Hi @aarola

You are better off using an actual date field for the axis.  That will stop you needing to scroll left and right.

If you use the FORMAT function, you are converting your date to a TEXT value, which won't auto scale on the axis.

Hi @Phil_Seamark,

Thank you for your answer. I am trying to compare my data between weeks. That's what I am trying to do:

That's why I cannot have a "real" date, I just want to compare mondays all together.

@aarola,

It is not possible to convert your field from text to date type as the values in the field are not valid dates.

Consider to use real date field as other post, or reduce the rows in your table.
