When I select time as aggregation type, it seems that the time zone in histogram is not the same as the time zone I used in the normal trend view. It seems that time zone in the histogram has a default value. But there is no way that I can know. For example, I had some discrete signal, I want sum them by day, I use two methods, signal from condition and histogram. But I can not get them follow each other. I even filter the signal to have it only to show a value a day. And found the aggregate from the histogram offsets. I think it is time zone setting that caused this problem. But I can't change the time zone in the histogram. Is there a way to do it? For instance, as below picture shows, Nov 14th, the signal has only a sample value 9708.1s(blue bar), the signal from condition gives the right summation(yellow bar) at the correct time Nov 14. But histogram gives the right value but on the different day 13th. Even some time it can't provide the correct value.

Hi Joe, Thank you for your reply, My capsules have both properties, but they are mergeproperties. I tried again with indepent properties rather than mergedproperties. It works. So Concatenating mergeproperties to be a new property is not supported, right? you can only get the first parameter of your fomular "Add". Is there a way to overcome this?

For a capsule, I have two properties of my interest, "product_S", "previous_product_S". I want to concatenate these two together to be a new property called "switch". How can I do it? My formular looks like this: $a3=$a1.mergeproperties($a2,"batch_S") $a3.transform( $cap->{ $c=add($cap.property("previous_product_S"),$cap.property("product_S")) $cap.setProperty("switch",$c)} ) But I only get the first part as the value of my new property "switch".
